Supporting English Language Learners
Promoting Language and Content Development
The purpose of this document is to nudge the field forward by offering support to the next generation of mathematics learners and by challenging persistent assumptions about how to support and develop students’ disciplinary language. The goal is to provide guidance to mathematics teachers for recognizing and supporting students’ language development processes in the context of mathematical sense making. UL/SCALE provides a framework for organizing strategies and special considerations to support students in learning mathematics practices, content, and language. The framework is intended to help teachers address the specialized academic language demands in math when planning and delivering lessons, including the demands of reading, writing, speaking, listening, conversing, and representing in math (Aguirre & Bunch, 2012). Therefore, while the framework can and should be used to support all students learning mathematics, it is particularly well-suited to meet the needs of linguistically and culturally diverse students who are simultaneously learning mathematics while acquiring English.
Theory of Action
Systemic barriers for language learners persist not only in tasks and materials, but in educators’ presentational language, expectations for peer interactions, and assessment practices. Only through intentional design of materials, teacher commitments, administrative support, and professional development can language development be built into teachers’ instructional practice and students’ classroom experience. Our theory of action for this work is grounded in the interdependency of language learning and disciplinary learning, the central role of student agency in the learning process, the importance of scaffolding routines that foster students’ independent participation, and the value of instructional responsiveness in the teaching process.
Mathematical understandings and language competence develop interdependently. Deep disciplinary learning is gained through language, as it is the primary medium of school instruction. Ideas take shape multi-modally, through words, texts, illustrations, conversations, debates, examples, etc. Teachers, peers, and texts serve as language resources for learning. Content teachers (implicitly/explicitly) teach the language of their discipline. Instructional attention to this language development, historically limited to vocabulary instruction, has now shifted to also include instruction around the demands of argumentation, explanation, analyzing purpose and structure of text, and other disciplinary discourse.
Students are agents in their own mathematical and linguistic sense-making. One prevailing assumption is that mathematical language proficiency means using only formal definitions and vocabulary. Although that is how math is often more formally presented in textbooks, this type of language does not reflect the process of exploring and learning mathematics. Another common assumption is that developing the language of the discipline requires continuous “time-outs” from the content, and multiple detours into “math language” mini-lessons. However, through successive and supportive experiences with math ideas, learners make sense of math with their existing language toolkit, while also expanding their language repertoire with tools and mathematics conventions as they come to see these tools (e.g., definitions, properties, procedures) as useful in accomplishing a meaningful goal.
UL/SCALE challenges both of these assumptions because they see “language as action”: in the very doing of math, students have naturally occurring opportunities to learn and notice mathematical ways of making sense and talking about ideas and the world. It is our responsibility as educators to structure, highlight, and bolster these opportunities, making explicit the many different ways that mathematical ideas are communicated, rather than acting as “the keepers” or “the givers” of language. A commitment to help students develop their own command of the “mathematical register” is therefore not an additional burden on teachers, but already embedded in a commitment to supporting students to become powerful mathematical thinkers and ‘do-ers’.
Scaffolding provides temporary supports that foster student autonomy. Some educators hold a more traditional assumption that students will learn the English language and disciplinary language by merely being immersed in them over time, with little additional support. This presents serious equity and access issues that cannot go unchallenged. Disciplinary language development occurs when students use their developing language to make meaning and engage with challenging disciplinary content understandings that are beyond students’ mathematical ability to solve independently. However, these tasks should include temporary supports that students can use to make sense of what is being asked of them and to organize their thinking. Learners with emerging language – at any level – can engage deeply with central disciplinary ideas under specific instructional conditions. Temporary supports, or scaffolds, can include teacher modeling, supporting students in making charts with mathematical information from a word problem, providing manipulatives or graphic organizers to support sense-making, identifying and drawing upon students’ inner resources, and structured peer interactions. Immediate feedback from intentionally-designed peer interaction helps students revise and refine not only the way they organize and communicate their own ideas, but also the way they ask questions to clarify their understandings of others’ ideas.
Instruction supports learning when teachers respond to students’ verbal and written work. The mathematics language routines described later in this document help both teachers and students keep one eye and ear on language as much as possible, focusing attention to student language that support in-the-moment teacher, peer, and self-assessment. Teachers can adapt and respond more effectively to what students are saying and doing as they develop disciplinary language and content understanding concurrently.
Based on their observations of student language, teachers can make adjustments to their teaching and provide additional language scaffolding where necessary. Teachers can select from the “heavier” or “lighter” supports provided in the curriculum as appropriate. When selecting from these supports, teachers should take into account the language demands of the task in relation to their students’ English language proficiency.
This framework includes four design principles for promoting mathematical language use and development in curriculum and instruction. The design principles and related routines work to make language development an integral part of planning and delivering instruction while guiding teachers to amplify the most important language that students are expected to bring to bear on the central mathematical ideas of each unit. The design principles, elaborated below, are:
Design Principle 1: Support sense-making
Design Principle 2: Optimize output
Design Principle 3: Cultivate conversation
Design Principle 4: Maximize linguistic and cognitive meta-awareness
These four principles are intended as guides for curriculum development and planning and execution of instruction, including the structure and organization of interactive opportunities for students, and the observation, analysis, and reflection on student language and learning. The design principles motivate the use of mathematical language routines, described in detail below, with examples. The eight routines included in this document are:
MLR1: Stronger and Clearer Each Time
MLR2: Collect and Display
MLR3: Critique, Correct, and Clarify
MLR4: Information Gap
MLR5: Co-Craft Questions and Problems
MLR6: Three Reads
MLR7: Compare and Connect
MLR8: Discussion Supports
Principle 1. SUPPORT SENSE-MAKING: Scaffold tasks and amplify language so students can make their own meaning.
Students do not need to understand a language completely before they can start making sense of academic content and negotiate meaning in that language. Language learners of all levels can and should engage with grade-level content that is appropriately scaffolded. Students need multiple opportunities to talk about their mathematical thinking, negotiate meaning with others, and collaboratively solve problems with targeted guidance from the teacher. In addition, teachers can foster students’ sense-making by amplifying rather than simplifying, or watering down, their own use of disciplinary language.
Teachers should make language more “considerate” to students by amplifying rather than simplifying speech or text. Simplifying includes avoiding the use of challenging texts or speech. Amplifying means anticipating where students might need support in understanding concepts or mathematical terms, and providing multiple ways to access those concepts and terms. For example, organizing information in a clear and coherent way, providing visuals or manipulatives, modeling problem-solving, engaging in think-alouds, creating analogies or context, and layering meaning are all ways to amplify teacher language so that students are supported in taking an active role in their own sense-making of mathematical relationships, processes, concepts and terms.
Several routines can be used to support sense making. In particular, MLR2 - Collect and Display, MLR6 – Three Reads, and MLR8 – Discussion Supports.
Principle 2. OPTIMIZE OUTPUT: Strengthen the opportunities and supports for helping students to describe clearly their mathematical thinking to others, orally, visually, and in writing.
Linguistic output is the language that students use to communicate their ideas to others. Output can come in various forms, such as oral, written, visual, etc. and refers to all forms of student linguistic expressions except those that include significant back-and-forth negotiation of ideas. (That type of conversational language is addressed in the third principle.)
Students need repeated, strategic, iterative and supported opportunities to articulate complex mathematical ideas into words, sentences, and paragraphs. They need spiraled practice in (a) making their ideas stronger with more robust reasoning and examples, and (b) making their ideas clearer with more precise language and visuals. They need to make claims, justify claims with evidence, make conjectures, communicate their reasoning, critique the reasoning of others, and engage in other mathematical practices. Increasing the quality and quantity of opportunities to describe mathematical reasoning also will allow teachers to frequently formatively assess students’ content learning and language use so that teachers can provide feedback and differentiate instruction more effectively.
Several routines can be used to Optimize Output. In particular, MLR1 – Stronger and Clearer, MLR3 – Critique, Correct, and Clarify, MLR4 – Info Gap, MLR5 – Co-craft Questions and Problems, and MLR7 – Compare and Connect.
Principle 3. CULTIVATE CONVERSATION: Strengthen the opportunities and supports for constructive mathematical conversations (pairs, groups, and whole class).
Conversations are back-and-forth interactions with multiple turns that build up ideas about math. Conversations act as scaffolds for students developing mathematical language because they provide opportunities to simultaneously make meaning and communicate that meaning. They also allow students to hear how other students express their understandings. When students have a reason or purpose to talk and listen to each other, interactive communication is more authentic. For example, when there is an “information gap,” in which students need or want to share their thoughts (which are not the same), students have a reason or purpose in talking and listening to each other.
During effective discussions, students pose and answer questions, clarify what is being asked and what is happening in a problem, build common understandings, and share experiences relevant to the topic. As mentioned in Principle 2, learners must be supported in their use of language, including within conversations, to make claims, justify claims with evidence, make conjectures, communicate reasoning, critique the reasoning of others, and engage in other mathematical practices – and above all, to make mistakes. Meaningful conversations depend on the teacher using lessons and activities as opportunities to build a classroom culture that motivates and values efforts to communicate.
Many routines can be used to Cultivate Conversation. In particular, MLR1 – Stronger and Clearer, MLR3 – Critique, Correct, and Clarify, MLR4 – Info Gap, MLR5 – Co-craft Questions and Problems, MLR7 – Compare and Connect, and MLR8 – Discussion Supports.
Principle 4. MAXIMIZE META-AWARENESS: Strengthen the “meta-” connections and distinctions between mathematical ideas, reasoning, and language.
Language is a tool that not only allows students to communicate their math understanding to others, but also to organize their own experience, ideas, and learning for themselves. Meta-awareness is consciously thinking about one's own thought processes or language use. Meta-awareness develops when students and teachers engage in classroom activities or discussions that bring explicit attention to what students need to do to improve communication and/or reasoning about mathematical concepts. When students are using language in ways that are purposeful and meaningful for themselves, in their efforts to understand – and be understood by – each other, they are motivated to attend to ways in which language can be both clarified and clarifying.
Meta-awareness in students is strengthened when, for example, teachers ask students to explain to each other the strategies they brought to bear to solve a challenging multi-step problem. They might be asked, “How does yesterday’s method connect with the method we are learning today?,” or, “What ideas are still confusing to you?” These questions are metacognitive because they help students to reflect on their own and others’ learning of the content. Students can also reflect on their expanding use of language; for example, by comparing the differences between how an idea is expressed in their native language and in English. Or by comparing the language they used to clarify a particularly challenging mathematics concept with the language used by their peers in a similar situation. This is called metalinguistic because students reflect on English as a language, their own growing use of that language, as well as on particular ways ideas are communicated in mathematics. Students learning English benefit from being aware of how language choices are related to the purpose of the task and the intended audience, especially if an oral or written report is required. Both the metacognitive and the metalinguistic are powerful tools to help students self-regulate their academic learning and language acquisition.
Many routines can be used to develop and formatively assess students’ meta-cognitive and meta-linguistic awareness. In particular, MLR2 - Collect and Display, MLR3 – Critique, Correct, and Clarify, MLR5 – Co-craft Questions and Problems, MLR6 – Three Reads, MLR7 – Compare and Connect, and MLR8 – Discussion Supports, lend themselves well to having students place extra attention on the language used to engage in mathematical communication and reasoning.
ELL Mathematical Language Routines
The eight mathematical language development routines included here were selected because they are the most effective and practical for simultaneously learning mathematical practices, content, and language. These routines also can be used in most lessons and across grade levels.A “math language routine” refers to a structured but adaptable format for amplifying, assessing, and developing students’ language. The routines emphasize the use of language that is meaningful and purposeful, not inauthentic or simply answer-based. These routines can be adapted and incorporated across lessons in each unit to fit the mathematical work wherever there are productive opportunities to support students in using and improving their English and disciplinary language.
These routines facilitate attention to student language in ways that support in-the-moment teacher-, peer-, and self-assessment. The feedback enabled by these routines will help students revise and refine not only the way they organize and communicate their own ideas, but also ask questions to clarify their understandings of others’ ideas.
MLR1: Stronger and Clearer Each Time
Purpose: To provide a structured and interactive opportunity for students to revise and refine both their ideas and their verbal and written output. This routine provides a purpose for student conversation as well as fortifies output. The main idea is to have students think or write individually about a response, use a structured pairing strategy to have multiple opportunities to refine and clarify the response through conversation, and then finally revise their original written response. Throughout this process, students should be pressed for details, and encouraged to press each other for details.
Example 1. Successive Pair Shares
- PRE-WRITE: Have students, individually, look at a problem and write down their idea/reasoning for solving the problem a certain way, or any thoughts or questions about it, in complete sentences if possible. This is the pre-write sample; there will be a post-write to see if the sharing with others makes a difference.
- THINK TIME: Then give a minute for students to think about what they will say to the first partner to explain what they are doing, or did, to solve it. (They can’t look at what they wrote while talking).
- STRUCTURED PAIRING: Use a successive pairing structure. (For example: Have students get into groups of 6 or 8, with inner circles of 3 or 4 facing outer circles of 3 or 4). Remind students that oral clarity and explaining reasoning are important. Even if they have the right answer or they both agree, the goal is either (1) to be able to clearly explain it to others as a mathematician would or (2) for the other person to truly understand the speaker’s ideas. Goal (1) is appropriate when students are further along in the development of a concept; goal (2) is appropriate closer to when students are first introduced to a concept.
- IN PAIRS: When one partner is listening, he or she can ask clarifying questions, especially related to justifying (Why did you do that?…). The other person then also shares and the listener also asks clarifying questions to draw more language and ideas out of quiet partners, if needed.
- SWITCH: Partners switch one, two, or three more times, strengthening and clarifying their idea each time they talk to a new partner. Optionally, turns can emphasize strength (focus on math concepts and skills) or clarity (how to describe the math to others).
- POST-WRITE: Have students return to seats and write down their final explanations, in sentences (they can use drawings, too, explained by sentences). Turn in.
MLR2: Collect and Display
Purpose: To capture students’ oral words and phrases into a stable, collective reference. The intent of this routine is to stabilize the fleeting language that students use during partner, small-group, or whole-class activities in order for student’s own output to be used as a reference in developing their mathematical language. The teacher listens for, and scribes, the student output using written words, diagrams and pictures; this collected output can be organized, revoiced, or explicitly connected to other language in a display for all students to use. This routine provides feedback for students in a way that increases accessibility while simultaneously supporting meta-awareness of language.
Example 1. Gather and Show Student Discourse
During pair/group work, circulate and listen to student talk during pair work or group work, and jot notes about common or important words and phrases, together with helpful sketches or diagrams. Scribe students’ words and sketches on visual display to refer back to during whole class discussions throughout the unit. Refer back to these words, phrases, and diagrams by asking students to explain how they are useful, asking students to clarify their meaning, and asking students to reflect on which words and visuals help to communicate ideas more precisely.
Example 2. Oral to Written Math Explanation
- POSE: Pose a substantive math question, one that is discussion-worthy.
- JOT: Allow students a few minutes to jot down notes quietly
- COMPARE: Allow students to compare responses (teacher listens closely)
- ELICIT: Ask for a volunteer or select a student to give oral explanation (several students might contribute), or provides a mock-up explanation with a common error
- SCRIBE: Teacher scribes the student explanation – asking for confirmation (often students will revise and improve)
- STUDENT FEEDBACK: Do you agree with the explanation? What is helpful? What questions do you have? What suggestions do you have to improve?
- TEACHER FEEDBACK: Teacher highlights a point that was not mentioned (strengths and areas for improvement), points out vocab, forms
- STUDENTS REVISE: Students revise their initial jottings in their journals, using the information that was provided in the class discussion.
MLR3: Critique, Correct, and Clarify
Purpose: To give students a piece of mathematical writing that is not their own to analyze, reflect on, and develop. The intent is to prompt student reflection with an incorrect, incomplete, or ambiguous written argument or explanation, and for students to improve upon the written work by correcting errors and clarifying meaning. This routine fortifies output and engages students in meta-awareness. Teachers can demonstrate with meta-think-alouds and press for details when necessary.
Example 1. Critique a Partial or Flawed Response
- PRESENT: Present a partial/broken argument, explanation, or solution method. Teacher can play the role of the student who produced the response, and ask for help in fixing it.
- Given response could include a common error.
- Given response should include an ambiguous term or phrase, or an informal way of expressing a mathematical idea.
- PROMPT: Prompt students to identify the error(s) or ambiguity, analyze the response in light of their own understanding of the problem, and work both individually and in pairs to propose an improved response.
- SHARE: Pairs share out draft improved response.
- REFINE: Students refine their own draft response.
Example 2. Always-Sometimes-Never
Use a structure or graphic organizer to evaluate or critique whether mathematical statements are always, sometimes, or never true. (Examples: “A rectangle is a parallelogram” or “A negative integer minus another negative integer equals a positive integer.”) Use the graphic organizer to frame and assess the reasoning process as students work toward evaluating and improving a response.
MLR4: Information Gap
Purpose: To create a need for students to communicate. This routine allows teachers to facilitate meaningful interactions by giving partners or team members different pieces of necessary information that must be used together to solve a problem or play a game. With an information gap, students need to orally (and/or visually) share their ideas and information in order to bridge the gap.
Example 1. Info Gap Cards
In one version of this activity, Partner A has the general problem on a card, and Partner B has the information needed to solve it on the “data card.” Data cards can also contain diagrams, tables, graphs, etc. Partner A needs to realize what is needed and ask for information that is provided on Partner B’s data card. Partner B should not share information unless Partner A specifically asks for it. Neither partner should read their cards to one another nor show their cards to their partners. As they work the problem, they justify their responses using clear and connected language.
- READ, then THINK-ALOUD: The problem card partner (Partner A) reads his or her card silently and thinks aloud about what information is needed. Partner B reads the data card silently.
- QUESTION 1: Partner B asks, “What specific information do you need?” Partner A needs to ask for specific information from Partner B.
- QUESTION 2: When partner A asks, Partner B should ask for justification: “Why do you need that information?” before telling it to Partner A.
- EXPLANATIONS: Partner A then explains how he or she is using the information to solve the problem. Partner B helps and asks for explanations, even if he or she understands what Partner A is doing.
- FOLLOW-UP: As a follow-up step, have both students use blank cards to write their own similar problem card and data card for other pairs to use.
Example 2. Info Gap Games
Students play a guessing game or matching game in which they have a real reason to talk (e.g., students need to work together to develop a strategy to win a game; each student is provided with different information; one student has something in mind and other students use their understanding of a mathematical concept to guess what it is).
Example: Guess my ratio. One student identifies a ratio between two distinct features/objects in a given set and keeps it a secret; other students try to figure out which features/objects are in the identified ratio.
MLR5: Co-Craft Questions and Problems
Purpose: To allow students to get inside of a context before feeling pressure to produce answers, and to create space for students to produce the language of mathematical questions themselves. Through this routine, students are able to use conversation skills as well as develop meta-awareness of the language used in mathematical questions and problems. Teachers should push for clarity and revoice oral responses as necessary.
Example 1. Co-Craft Questions
- PRESENT SITUATION: Teacher presents a situation – a context or a stem for a problem, with or without values included. (Example: A bird is flying at 30 mph)
- STUDENTS WRITE: Students write down possible mathematical questions that might be asked about the situation. These should be questions that they think are answerable by doing math. They can also be questions about the situation, information that might be missing, and even about assumptions that they think are important. (1-2 minutes)
- PAIRS COMPARE: In pairs, students compare their questions. (1-2 minutes)
- STUDENTS SHARE: Students are invited to share their questions, with some brief discussion. (2-3 minutes)
- REVEAL QUESTIONS: The actual questions students are expected to work on are revealed, and students are set to work.
Example 2. Co-Craft Problems
- PAIRS CREATE NEW PROBLEMS: Students get into pairs and co-create problems similar to a given task.
- STUDENTS SOLVE THEIR OWN PROBLEMS: Students solve their own problems before trading them with other pairs.
- EXCHANGE PROBLEMS: Students solve other pairs’ problems, and check solutions and methods with the pair who created each problem.
- TOPIC SUPPORT: Teacher can provide possible topics of interest to students, or brainstorm as a whole class for 2 minutes before pairing up.
MLR6: Three Reads
Purpose: To ensure that students know what they are being asked to do, and to create an opportunity for students to reflect on the ways mathematical questions are presented. This routine supports reading comprehension of problems and meta-awareness of mathematical language. It also supports negotiating information in a text with a partner in mathematical conversation.
Students are supported in reading a situation/problem three times, each time with a particular focus:
- Students read the situation with the goal of comprehending the text (describe the situation without using numbers),
- Students read the situation with the goal of analyzing the language used to present the mathematical structure.
- Students read the situation in order to brainstorm possible mathematical solution methods.
This routine works well in conjunction with Mathematical Language Routine 5, in which the question stem is tentatively withheld in order to focus on the comprehension of what is happening in the text.
MLR7: Compare and Connect
Purpose: To foster students’ meta-awareness as they identify, compare, and contrast different mathematical approaches, representations, and language. Teachers should demonstrate thinking out loud (e.g., exploring why we one might do/say it this way, questioning an idea, wondering how an idea compares or connects to other ideas and/or language), and students should be prompted to reflect and respond. This routine supports meta-cognitive and meta-linguistic awareness, and also supports mathematical conversation.
Example 1. Compare and Connect Solution Strategies
Instructional time is dedicated to students understanding one another’s solution strategies by relating and connecting other students’ approaches to their own approach.
- SET-UP: Ways to set this up so that multiple strategies are likely to be generated by each pair of students:
- I solve it one way, you solve it another.
- Divide and conquer: you do one and I do another.
- I have a piece of info, you have a piece of info.
- WHAT IS SIMILAR, WHAT IS DIFFERENT: Students first identify what is similar and what is different about the approaches. This can also be an initial discussion about what worked well in this or that approach, and what might make this or that approach more complete or easy to understand.
- MATHEMATICAL FOCUS: Students are asked to focus on specific mathematical relationships, operations, quantities and values. For example:
- Why does this approach include multiplication, and this one does not?
- Where is the 10 in each approach?
- Which unit rate was used in this approach?
MLR8: Discussion Supports
Purpose: To support rich discussions about mathematical ideas, representations, contexts, and strategies. The examples provided can be combined and used together with any of the other routines. They include multi-modal strategies for helping students comprehend complex language and ideas, and can be used to make classroom communication accessible, to foster meta-awareness of language, and to demonstrate strategies students can use to enhance their own communication and construction of ideas.
- Revoice student ideas to demonstrate mathematical language use by restating a statement as a question in order to clarify, apply appropriate language, and involve more students.
- Press for details in students’ explanations by requesting for students to challenge an idea, elaborate on an idea, or give an example. This is intended to get more participation from students, deepen student understanding, and provide extensions.
- Show central concepts multi-modally by utilizing different types of sensory inputs: acting out scenarios or inviting students to do so, showing videos or images, using gesture, and talking about the context of what is happening.
- Practice phrases or words through choral response.
- Think-Aloud Demonstrating
Teacher uses a think-aloud to raise students’ awareness about their mathematical language and thinking. Teacher talks through his thinking about a new mathematical concept as he solves a related problem or does a task. While doing so she demonstrates detailing her steps, describing and justifying her reasoning, and questioning her strategies. Students’ attention is brought to the importance of describing their thinking to others. They are then allowed opportunities (possibly in conjunction with other routines) to talk through their own thinking.
A few discussion starters include:
- How can you remember that word or term?
- What was most confusing about the math concepts we explored today?
- What was most/least challenging for me to learn? Why?
- Is this always true? Sometimes true?
- How does stronger, clearer each time help you to develop your math and language skills?
- What things did we do in class today that help you think about how to solve the problems?
