## 3D PRINTED MATH

If you have access to a 3D Printer, try printing toys, gadgets, puzzles, and math manipulatives.

Creativity is a major part of growing up, and 3D printed toys can let kids express that. Everyone can design 3D models to print or visit websites like Thingiverse to find free models to customize or print directly. You can support the designer by clicking the tip the designer button.

Do not worry that if you cannot 3D print, you can still purchase the one-of-a-kind 3D models.
