We are going to walk you through a process that shows you the benefit of thinking about programming tasks in terms of writing functions.

• Over the next 3 levels we are going to write a program that draws the figure shown at right which sort of looks like a jagged diamond shape.

• If you look at this image you might recognize elements that repeat: this is a 4-sided figure, and each side is made up of some zig-zag steps.

• We're going to break the programming down into useable parts and then use those parts as building blocks to make this more complex drawing.

• First let's define a function that draws just one of these zig-zag steps. We've started you out with a definition of right() that you can use...

Do This:

Define a function named function drawStep() which makes the turtle move forward and left as shown.

Note: at the end the turtle should be facing the same direction it started.
