DS and I made up this finger math game where you use sign language numbers (so you can go from 1 - 10 using one hand). So one person makes a number in each hand and then the other person says which is greater or if they're equal too. We started really simple with the ability to do positive and negative numbers (an upside down hand means negative) and then we added a sign to denote adding two numbers together. By the end of the week it *really* complex ... you could do all the basic math operations and squares and cubes. We still play that game at bath time.
