Learning to go Loopy!

OK, it's time to get back to our turtle and learn a few more computer programming concepts!

Right-click on this link to AJLogo (our Turtle Graphics commander) and open it in a new window. Last week we followed the first tutorial and saw how to begin drawing on the screen. First, in the command window, type

• clearscreen
• showturtle
• pendown

and then have a go at drawing a simple shape. If you can't remember, you might want to look back over the first tutorial. Otherwise, type 'home' in the commander window and get ready for the second tutorial!

This time, we're going to learn about the power of computer programming: repitition (loops) and procedures! There might be a lot of new concepts in this second tutorial, so don't feel alone if you feel like you're swimming! When you've finished the exercises (you might need to help each other!), write up your experiences on your blog! Try to cover the following:

• how you found the tutorial,
  
• why repitition is powerful
• why procedures are helpful
