Objectives |
| Children should learn: |
- key ideas: that the screen turtle can be given commands to produce a specific shape on screen
- that the turtle can be moved before it starts drawing
- techniques: to write a list of commands to produce a pre-drawn shape
- to use pendown and penup to move the turtle

Outcomes |
|
Children: |
- Provide two examples of letters (eg E or M) that can be drawn with the screen turtle using only 45 or 90 degrees; use graph paper (1cm2) to draw the letters. Show the class how to draw the two letters and explain how each square on the graph paper measures 50 screen turtle steps. Demonstrate how to write instructions to produce the two letters on screen.
- Ask children to draw the first letter of their name on a piece of graph paper and get them to write the instructions for the screen turtle. When children have completed their sequences produce the example letters, but use penup and pendown to move the turtle to the left of the screen before doing the first letter and then to the right of the screen to do the second letter. Show the children how to print their work. Divide the children into pairs and ask each pair to create their initials on screen and print the results.
