Thanks for the suggestion! I played that with my son this morning as I was cooking breakfast (just positives and some x-and-a-half numbers) and he loved it and didn't want to stop. It's pretty easy for him at that level, but I see how you can make it much more complicated. Of course almost-3-yr-old sister insisted on turns as well, which didn't work quite so smoothly. Excuse my ignorance, but what's a cuisenaire rod? Still eager to hear any other thoughts as well.
