## Session 09

Today's class was a little more informal and dynamic in class. Below are my general notes of what I inteneded to discuss. This may or may not match what we actually did depending on what you guys said/asked.

Let's begin by looking at two different POSSIBLE solutions for Activity 1.2 from last week. Let's make sure we talk about the difference again between absolute and a relative motion solution.

and

Notice that this first one has a lot of "duplicate" code. This is something that makes itself perfect for a loop.

Let's play with this last one for a little bit. Once you have Square tracer with a loop it gets really easy to make a variety of other shapes:

1. Look at how different combinations of repeat, turn and length amount can create other shapes:
2. 4, 90, 100 (square)
3. 8, 90, 100 (doesn’t make an octagon, makes a square twice)
4. 8, 45, 100 (tries to make a square, but gets squished when it hits the edges
5. 8, 45, 50 (octagon)
6. 3, 120, 150 (triangle)
7. 6, 60, 75 (hexagon)
8. 360, 1, 1 (circle)
