Lesson Purpose

The purpose of this lesson is to activate the strategies students have for subtracting numbers within 1,000.

Lesson Narrative

In grade 2, students subtracted numbers within 1,000 using various strategies based on place value and the associative and commutative properties of addition. They used base-ten blocks, base-ten diagrams, equations, and number lines to represent their reasoning.

In this lesson, they review a variety of strategies with an emphasis on subtracting hundreds and hundreds, tens and tens, and ones and ones. Students should have access to base-ten blocks.
