This was my first experience with Moon Dough although I have played around with Moon Sand a little. The kids thought that it was fun and a good substitute for playdough. I just love how light it is, like styrofoam.
You can practice some academic skills with this by making shapes, letter and numbers. Also, you can throw in some science by having them compare Moon Dough and Play Dough (or any other substance such as Oobleck, flubber, slime, etc). Have them describe how it feels, the texture, how it smells, how it moves, molds or pours, etc. But whatever you do, don't forget the most important thing, have fun!
