A 2-player, GeoGebra version of Sara VanDerWerf's game. You will place (up to) 25 numbers in the grid. You score by placing (by clicking) matching numbers in adjacent squares.

How many dots are there? How do you see it?

Use this with the goal of students flexibly describing many ways of composing/decomposing a number.
