The best game for preschooler I’ve found so far is Cute Math.

Your little one can count baby penguins, pick the right amount of apples to put in a basket, move some happy birds around to solve addition problems, and drop apples off a tree to solve subtraction problems.
The best feature of this game is the modeling involved - all of the cute animals and objects become manipulatives that you can move around to help solve the problem. For instance, for the problem 3 + 4 = ___, there are 3 happy birds on one wire, and 4 happy birds on another. One tap of the screen sends all of the birds to one wire, and your child can easily count the birds altogether. Good stuff. Did I mention that it’s also cute?
