Preparation
Lesson Narrative
Students first match arrays to drawings of equal groups. Then they redraw drawings of equal groups as arrays. The work of this lesson connects to upcoming lessons when students represent arrays with expressions and equations.
Make connecting cubes or counters available to students who need them. Keep collecting ideas that arise about commutativity.
