Unit 2, Lesson 8

Make ten when one addend is 8.

EngageNY 60 min(s)
In this lesson, students use ten-frames and number bonds to add 8 and another single-digit number by decomposing the second addend to make ten with the 8. For example, they solve the problem "Amy wrote 8 letters to her friends. Peter wrote 3 to his friends. How many letters did they write?" by showing 8 dots and 2 dots together in a ten-frame, along with one extra dot, and by showing the decomposition of 3 into 2 + 1 as a number bond.
