1. Your first green diamond「turtle」

It's time to earn your first green diamond for this worksheet. This one will not be so tricky; it's just to get you familiar with Grok and the submission process. Simply follow these steps to complete the problem:

1. Drag and drop one of the 'Move forward 20 steps' blocks onto the empty workspace to the right of it. Anywhere in the white space will do.

2. Notice your instruction 'block' has just been translated into some Python code in the 'Code' tab below. In the next worksheet we'll be writing that code ourselves, but for now you can use the blocks to construct your program.

3. To run this program we've created and see what it does, hit the 'Run' button in the top right corner of the window.

4. Watch the 'Animation' tab below the program. You should see the turtle start in the middle of the screen, facing right. It should move 20 'turtle steps' to the right (the direction it is facing). It should leave a short black line behind it.

5. When you are ready, it's time to submit your program and get your first green diamond. Up near the 'Run' button, you will also see a 'Mark' button. Press this button now, and then press 'Submit' to check your answer.

   Note: if the 'Mark' button is not clickable, make sure you 'Run' your program first.
