I have been working on a teaching resource that uses art to teach math and math to teach art. This video demonstrates a hands-on art project that you can use to create a beautiful design that connects to geometry and patterning, and to some degree number sense. Rotational symmetry inherently demonstrates the art principals of pattern, rhythm, and unity/harmony. Mandalas are both calm and dynamic at the same time. Some designs create an effect of rotation, while others are more of an explosion. T
