Unit 1, Lesson 1

Analyze and describe embedded numbers (to 10) using 5-groups and number bonds.

EngageNY 60 min(s)

In this lesson, students decompose numbers into two visual sets and record their decompositions as number bonds. They use the 5-group configuration, as this organization allows students to quickly see a subset of 5. Once they have identified that first subset of 5, they can quickly recognize the other part. (For example, students split 8 into a group of 5 and another group of 3.) The teacher then guides students to count on from the 5 to determine the total.
