the Math Their Way newletter has tons of great ideas. I have only skimmed through this so far. I am planning on doing some more reading tonight. Don't miss the downloads on the bottom of the page. That alone is a great resource. The newsletter, has ideas on how to implement them... This looks very interesting. I also noticed in their store, they not only sale tons of items to implement a hands on math curriculum, but there is a curriculum book itself.
