Unit 1, Lesson 6# Subtract single-digit numbers from multiples of 10 within 100

EngageNY 60 min(s)

In this lesson, students advance their "take from ten" strategy to subtract single-digit numbers from multiples of ten. For example, 30 - 9 is solved by decomposing 30 as 20 and 10, taking from ten (10 - 9), and composing the parts that are left (20 + 1).
