Unit 4, Lesson 24

Use manipulatives to represent subtraction with decompositions of 1 hundred as 10 tens and 1 ten as 10 ones

EngageNY 60 min(s)

In this lesson, students continue to use decomposition of the minuend to subtract a two-digit number from a three-digit number. They use place-value disks to represent breaking apart three-digit minuends and subtract from the hundred. For example, students restate 143 - 90 as 100 - 90 + 43.
