Unit 5, Lesson 9

Relate manipulative representations to the addition algorithm

EngageNY 60 min(s)
In this lesson, students build fluency of adding numbers within 1,000. They relate the use of place-value disks on a place-value chart to the algorithm, recording compositions as new groups below in vertical form. As they move the manipulatives, students use number bonds to represent the relationship between the addends and the sum. They record this in the vertical form.
