There’s a problem solving conversation going on at Cake right now about determining the problems you shouldn’t invest your time trying to solve. Your use of Kickstarter campaign feedback sounds like a great approach for determining which problems (or opportunities) are worth pursuing.
Getting back to your initial statement, I wanted to ask one more question.
About playing with blocks.
Playing games is great. Playing with blocks is crucial, especially for young children, since there's a physical intuition that gets built that ends up providing fundamental analogies for mathematics.
My two year old grandson loves playing with blocks. Mostly, he likes telling me to build towers so that he can knock them all down and laugh about it. But sometimes he will start counting them as best he can. Any suggestions of games or activities to try with him during the next year? I thought of this game but I think it’s a few year’s off before he can compete with our third panelist’s daughter.
