We can so a different pedagogical approach.[br][br]Not only we can visualise but we can touch the mathematical representations of the objects that we are working with. [br][br]Also we can create our own materials that fit to our class and the way we tech.[br][br][br][br]
An idea that came to my mind when working with 3D printed objects was to print different simultaneous equations and using the prints to understand the concept of solution. Infinite solutions, impossible system, only one point in the solution.
Creating solid that do not come in the "normal" packages, special for our class.
We can also print functions to understand the concept of maximums and minimums, derivatives...
