Lesson 2

Patterns that Repeat

Lesson Purpose

The purpose of this lesson is for students to analyze, describe, extend, and generate visual patterns in which a series of symbols or shapes repeat by a rule, using structure and mathematical reasoning to do so.

Lesson Narrative

In an earlier lesson, students analyzed and described features of patterns that followed a rule. In this lesson, students do the same with designs with shapes that repeat according to a rule. Students begin by examining the patterns visually. They look for structure and make use of it to extend the patterns (MP7). Later, they represent each shape in the pattern with numbers and reason about the repetition mathematically—by using operations and observing the properties of the numbers (MP2). The third activity is optional as it provides an opportunity for extra practice.

Teacher Reflection Questions

In an upcoming section, students will learn to multiply multi-digit numbers. What do you notice in their work from today’s lesson that you might leverage in that future lesson?
