Lesson 9

How Much in Each Group? (Part 2)

Lesson Narrative

This lesson allows students to practice finding the amount in one group, and to interpret, represent, and solve different kinds of division problems with less scaffolding. In one activity, students are not explicitly told whether the division situations involve finding the number of groups or finding the amount in each group. They decide on an interpretation that would enable them to solve a division problem. Students are also required to identify relevant information (from a video, a picture, or written statements) that would help them answer questions. 

Because the tasks in this lesson are not scaffolded, students will need to make sense of the problems and persevere to solve them (MP1). As students move back and forth between the contexts and the abstract equations and diagrams that represent them, they reason abstractly and quantitatively (MP2).

Learning Goals

Teacher Facing

  • Interpret a situation (presented in written language or using other representations) involving equal-sized groups, and generate mathematical questions that could be asked about it.
  • Solve a problem involving division of fractions, and present the solution method (orally, in writing, and using other representations).

Student Facing

Let’s practice dividing fractions in different situations.

Learning Targets

Student Facing

  • I can find the amount in one group in different real-world situations.
