Help build your students subtraction skills by finding the unknown! This lesson will help your students understand the relationship between addition and subtraction, as students build towers to find unknown addends.

In this lesson, students will answer questions, role-play different scenarios, and explore their feelings as they make healthy choices. They will also learn some questions to ask themselves when making decisions.

Give students plenty of practice adding to 20 with this fun game! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Do Math with M&Ms lesson.
