## Array-Bow of Skittles and Multiplication Strategies

This lesson write-up is for teaching a two-digit by two-digit multiplication 3-Act Math lesson where students estimate the number of Skittles in a jar before using information and math to find a more accurate estimate. It uses Graham Fletcher’s Array-Bow lesson and while it addresses standard 4.NBT.5, it’s appropriate for 4th and 5th grade students of all levels. The write-up contains a lesson pathway with specific questions/moves to consider, analysis of the opportunities for student learning, and other wisdoms and insights we learned from teaching this lesson as a part of a lesson inquiry.

Give it a try with your own students. And then tell me how it went. Let’s make it better together.
