hmm. Well, we play Yahtzee at our house -- it's fun for probability and for multi-digit adding, though your ds is likely past that.

I'll be interested to read any responses! KG loves doing math that's intuitive for him (which is quite a bit) but rather balks at sitting and "learning" anything, especially on paper.

Following with interest!

Oh, and has he done any Rainforestmaths.com? Not sure what level your ds is working at, but that has a variety of topics that are presented simply and visually.
