The purpose of this lesson is for students to relate arrays to drawings of equal groups and describe arrays in terms of multiplication.
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.
- Relate arrays to drawings of equal groups and describe them in terms of multiplication.
