Who are we?
We are Dan Finkel and Katherine Cook, a husband and wife team devoted to transforming how math is taught and learned.

We develop math games and curriculum, including tons of free lesson plans that we give away here. We train teachers and produce professional learning materials. And we write puzzles, produce math-art shows, and do whatever we can to show people how playful, beautiful, and life-changing mathematics can be.
