## HMH Into Math Grade 4 Module 3 Lesson 1 Answer Key Explore Multiplicative Comparisons

I Can use visual models and equations to represent and interpret a multiplicative comparison.

**Spark Your Learning**

Jaslene throws 2 balls at the target. She gets 4 points for landing on red. She gets 3 times as many points for landing on green.

Use a visual model to show how many points Jaslene gets for landing on red. Then show how many points she gets for landing on green.

**Turn and Talk** How does your visual model show 3 times as many as 4? How could you use a different visual model to show the same comparison?
