Unit 1, Lesson 6

Represent put together situations with number bonds. Count on from one embedded number or part to totals of 8 and 9 and generate all expressions for each total.

EngageNY 60 min(s)

In this lesson, students focus on the 'put together' situation, showing various ways of decomposing 8, and counting on from one addend, or part, to find the total. They use pictures and 5-group cards to devise different decompositions, record their thinking with number bonds and expressions, and reflect on the relationships between different compositions of a number.
