I created these cubes for my daughters to play with and teach them how to do math. I have been able to teach my 5 and 3 year old how to add and substract from these. I created 1-20, then every 10 to 100 along with +, -, x, / & =. Since it worked so well, I figured I would share them here with everyone.
These go along with the Alphabet cubes and standard shape stencil I created, links to them here:
