Array Builder

Build multiplication arrays of any size, switch orientation, and reveal the total as repeated addition or a word problem.

Set any number of rows and columns
Switch orientation to show commutativity
Reveal the total as a repeated-addition sentence
Frame the same array as a word problem

The bridge between counting in groups and formal multiplication — build an array, watch it work, and see why turning it on its side doesn't change the total.
