**SYMMETRY**

**THE MORE IT CHANGES, THE MORE IT STAYS THE SAME**

### THE STORY ... coming soon!

See the trailer.

- For centuries, Martians have schemed to conquer Earth.
- Now they have a plan:
*Math + Coding Attack!* - Join Earthlings Pix & Vix as they explore math + coding with Martians Zork & Gork
- Prepare your brain before Martians turn it to mush.
- Study math. Learn code.

**WHAT IS SYMMETRY? (4.2 minutes)**

A symmetry is a transformation that leaves a shape looking unchanged.
