The linking party question over at Jasztalville: Where Inquiry and Creativity Rules is How do you make math hands on?
I love to provide games to reinforce skills. Check out an earlier post Games, Games, Games. I also was intrigued by 4th Grade Frolics vocabulators. I have put a little spin on these to work with my math units. I will post this as soon as I've got them finished.
Lastly, to make math "hands-on" we do a lot of moving. I play Simon-Says with geometry concepts, work in stations, and sing songs. You can find many great videos to go with math songs on YouTube! We have a lot of fun!
