Lesson objective: Represent numbers in two or more equivalent ways.

This lesson helps to build fluency with place value concepts. Drawing is used here because it supports students moving on from concrete (the base ten blocks) to more representational in the concept. This work develops students' understanding that three-digit numbers can be represented in different, but equivalent ways.

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they understand that three-digit numbers have more than one way to be represented; this comes with repeated experimentation with our place value system.

**Key vocabulary:**

- hundreds
- place value
- representions
- tens

**Special materials needed:**

- base ten blocks if needed
- recording sheet
