Painting With Loops
Loops
Let's look at the sequence for drawing a square from scratch:
 Put Pen Down
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Lift Pen Up
Do you recognize any pattern here?
Is anything repeating over and over?
 Put Pen Down
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Go Forward For 3 Rotations
 Turn Right
 Lift Pen Up
Those 2 lines are repeating 4 times...
When you detect patterns like these that repeat you can use Loops to simplify your code, so that the above becomes:
 Put Pen Down
 Repeat 4 Times
 Go Forward For 3 Rotations
 Turn Right
 Lift Pen Up
See the same transformation in Gears code blocks:
Can be simplified as:
Practice

You can try the above with this canvas

You can try to paint other polygons (triangle, pentagon, hexagon)  what changes do we need to make to our blocks to add sides to our shape?
