All the files necessary are available online. The project is open to new approaches and there is room for the imagination of everyone to help kids really understand math and make this product more complete.


Parents, older brothers, other kids can play the board game with smaller children and offer alternative solutions (so that kids understand that math is not just about one correct answer).
