IPad Apps for learning Math

As I work through the plethora of resources that are available from publishers, I continue to gravitate toward what the IPad has to offer.  There is nothing better than snuggling up to a great game in the IPad - the children can easily navigate through many of the activities and they are usually engaged because there are so many interesting apps that incorporate not only math content but also the child's interest.

Here are a few of my favorites:
Montessorium:

Let's Make Shapes: Fun tracing and drawing application for young children.

edu dice: teaches toddlers to do simple addition with two dice.
