Why these Math Tools?

This project started with a simple goal: accessibility in math class.

Every student has a unique way of thinking. Some students need a little more executive functioning support. These tools were built to carry that structure, so the thinking stays with the learner, where it belongs. The right tool, in the right moment, can make all the difference between a student who feels stuck and one who feels capable.
