It's an amazing idea! I'm always looking for screen-free activities related to problem solving with my daughter. By the way, if someone happens to have other examples, it would be great to share!
My daughter wants me to teach him how to play go at some point, but he’s not quite ready for that. He hasn’t yet learned the concept of winning or losing at games, and we don’t see any need to force that on him early. In the meantime, playing with and talking about the stones seems to have boosted his understanding of numbers.
