EngageNY10 min(s)

This Problem Set is a part of the Lesson 7, Unit 1, Grade 1. In this lesson, students focus on the 'put together' situation, showing various ways of decomposing 9, and counting on from one addend, or part, to find the total. They use pictures, 5-group cards, and linking cubes to devise different decompositions, record their thinking with number bonds and expressions, and reflect on the relationships between different compositions of a number.
