**SYMMETRY**

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

**CODING APPS**

We have 3 coding environments to try:

See descriptions below The Story section.

### THE STORY ... coming soon!

- 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.

### ROTATION & REFLECTION SYMMETRIES

- What happens when you combine symmetries?
- Use code to control symmetry combinations
- Try it at

**BUMPER SYMMETRIES WITH SQUARES**

- What happens when symmetries of the square bump together and apply their transformations to one another?
- Use code to control bumper symmetries with squares
- Try it at
**mathsurprise.ca/apps/sym/bumper-squares**

**BUMPER SYMMETRIES WITH TRIANGLES**

- What happens when symmetries of the triangle bump together and apply their transformations to one another?
- Use code to control bumper symmetries with triangles
- Try it at

**CLASSROOM DOCUMENTARY**

From a Grade 2/3 classroom.

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

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