This document provides an introduction to computer programs and coding using TouchDevelop. It explains that programs allow you to create code sequences to draw shapes and control a turtle. The document encourages experimenting with changing turtle properties like speed and color or drawing more complex shapes. It also introduces the concept of using loops with counters to repeat code sequences.

1.  What is a computer program?
 What does it look like?
 How does it work?
 Can I make one?

2. Code

3. Get started with TouchDevelop
 You MUST use Google Chrome
 You will need a Google or
Hotmail/Microsoft account to
register
 www.touchdevelop.com

5. Boring Turtle

6. Clever Turtle

7. Can you ……
 Make bigger and smaller squares?
 Change the turtle’s colour?
 Change the turtle’s speed?
 Draw a spiral, with each line slightly
bigger than the one before?
 Draw hexagons?

8. What we’ve learned
 Our first App!
 Code follows a sequence
 We can loop in the sequence
 for [min] < counter < [max]
 do things …..
 end For
 What is ‘counter’?
