We are all born mathematicians wired for testing conjectures and discovering patterns. When we solve a puzzle we experience just as much joy as when we dance, make art or listen to stories.
Our aim is to create opportunities for children to practice their innate mathematical thinking skills while delighting in playful problem-solving for fun.
This whole project is a labor of love sitting at the intersection of three of our favorite things to do:
Problem-solving for fun,
Designing learning experiences for children,
and Watching them learn.
In particular we love to create stress-free spaces where children can play with mathematical ideas through games and puzzles. It is definitely one of our favorite ways to connect with young minds around the world, and it helps them connect to each other across borders through a shared joy of solving problems just for the fun of it.
