Has anyone had any success--or desire--to use manipulatives (not virtual) for supplementing high school level courses?
Would be interested in any and all comments.
Note: I found some work by Prof. James Sandefur with "Hands-on Mathematics". He uses physical objects in teaching modules that resemble simple physics labs (but require no significant scientific understanding.
Fundamental mathematical principles aren't necessarily examined, but these modules give you a great way to see mathematics applied in the real world without having extensive specialized knowledge in a particular area.
I don't know the prof. and have nothing to do with his research. Just thought it was interesting, and was wondering if any other math teachers have used this idea, or think using this approach is a good idea.
