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.
