Base 10 Chart for Multiplication

Base 10 blocks are a go to representation for place value. They are also easy to implement for addition or subtraction with place. With a group model, they are useful for multiplication and division. It is harder to model multiplication of multi-digit numbers with regrouping. This post presents a Google Jamboard with base 10 blocks on a scaffolded chart to provide such a model.

Overview

The structure aligns with the group representation of multiplication. The # of items in each group is presented first as this aligns with unit rate and slope problems.
