# Lesson 1

Estimation Explorations with Fractions

### Lesson Purpose

The purpose of this lesson is for students to practice reasoning about fraction representations through estimation.

### Lesson Narrative

In previous lessons, students learned how to represent fractions with area diagrams, fraction strips, and number lines. In this lesson, students revisit each of these representations in an estimation context. Students have an opportunity to think about how to partition each representation to decide what fraction is shown (MP7). Additionally, if time allows and it seems of benefit to student understanding, there is an option after each activity to find the exact value of the fraction in the task statement.

If students need additional support with the concepts in this lesson, refer back to Unit 5, Section A in the curriculum materials.

### Teacher Reflection Questions

Which fraction representations did students seem most comfortable with today? Which representations do you want to be sure to work more with before the year is over?
