1. The three pink blocks below draw a triangle, a square and an octagon. What are the difference? Why does the square block has a "Point in direction -90"? What's going to happen if you take that block out? Try in your Scratch account.
2. Can you create 2 more self-defined blocks to draw pentagons and hexagons?
3. Change the turn degree, moving steps and repeating times to different numbers to see what shape you can create.
