Student Achievement Partners10 min(s)

This Problem Set is a part of the Lesson 7, Unit 1, Grade 3. Lesson builds on the work with missing factors from the previous lesson, starting with situations of an unknown number of groups. Students work with concrete and pictorial representations and write them as missing factor equations. Problems will also introduce measurement situations in which the units represent the objects in equal groups in order to build a foundation for later work with measurement.
