# Lesson 8

Show Me All the Ways

### Lesson Purpose

The purpose of this lesson is for students to represent two-digit numbers in different ways to demonstrate place value understanding.

### Lesson Narrative

Students represent a two-digit number in as many ways as they can. They are encouraged to think about representations of their number that have different amounts of tens. Then, they do a gallery walk to compare representations their classmates made.

If students need additional support with the concepts in this lesson, refer back to Unit 4, Section D in the curriculum materials.

### Teacher Reflection Questions

In grade 2, students extend their understanding of place value to three-digit numbers and perform addition and subtraction within 1,000. How does the grade 1 work with place value prepare them for that future learning?
