I do a lot of mathematical play with my 4yo. I tell stories with mathematical concepts - anything involving money (selling and buying things) is popular around here. And the Boolean Logic Baby Gate was a big hit (you have to put in just the right filter function if you want to let your friends in but keep the disruptive babies out). https://bancosparenting.wordpress.com/2021/05/08/pickle-and-the-boolean-logic-baby-gate/ https://bancosparenting.wordpress.com/2021/05/08/pickle-and-... I sing Baa Baa Black Sheep but with lots of different numbers of wool distributed in different ways (this also keeps the 1yo entertained). https://wordpress.com/posts/bancosparenting.wordpress.com https://wordpress.com/posts/bancosparenting.wordpress.com Guess My Secret Number gets lots of requests: "If you have my secret number and you add four more, you get seven. What's my secret number?" (We take turns guessing and giving clues.) https://wordpress.com/posts/bancosparenting.wordpress.com https://wordpress.com/posts/bancosparenting.wordpress.com Another good game is Tiny Polka Dot - we've come up with so many of our own variations on the games. https://wordpress.com/posts/bancosparenting.wordpress.com https://wordpress.com/posts/bancosparenting.wordpress.com In terms of actual books, we really enjoy Life of Fred. https://www.rainbowresource.com/category/9813/Life-of-Fred.html https://www.rainbowresource.com/category/9813/Life-of-Fred.h...
