## HMH Into Math Grade 1 Module 6 Lesson 3 Answer Key Represent Addend Unknown Problems with Objects and Drawings

I Can solve word problems when one addend is unknown and represent the problem with objects, drawings, and equations.

**Spark Your Learning**

Robin has 12 peppers. 7 peppers are red and the rest are yellow. How many peppers are yellow?

How can you show this problem?

Answer:

Explanation:

Robin has 12 peppers
