Unit 2, Lesson 17

Model subtraction of 8 from teen numbers.

EngageNY 60 min(s)

In this lesson, students use linking cubes and drawings to compare strategies for subtraction. First, they take 8 from 15 by subtracting 5, and then 3 more. Then they use the "take from ten" strategy to quickly subtract 8 from 10, and add the 2 and the 5. Finally, they practice taking 8 from whole numbers 11-19.
