1. Using MIT Scratch for Programming and Control Exercise 5 – Drawing with Scratch
Year 9 ICT
Autumn Term 2007

2. What you will learn: Delete a sprite and import a new sprite
Draw using the Pen feature of scratch
Make a simple script to draw circles
Use the “pen up” and “pen down” feature
Change the colour of the pen
Set the start position of the sprite
Make a sprite appear and disappear using show and hide

3. Delete the cat sprite
Click the scissors button and delete the cat sprite

4. Browse for a new sprite
Click the centre button below the stage and browse for the drawing pencil sprite

5. Drawing pencil sprite The drawing pencil comes with a script
Investigate the drawing pencil script

6. Clear command Delete the script
Click the pen menu to investigate the options
Drag the clear command into the programming area

7. Drawing a circle Copy the script below to draw a small circle
(Hint 24 times 15 is 360) this repeat script will become a building block for more complex scripts

8. Drawing a circle
Move the drawing pen to a new position and draw a few more circles

9. Changing position automatically
Edit the script as shown
Double click the clear symbol and run the script

10. Changing colours Edit the script as shown
Double click the clear symbol and run the script

11. Setting the start position
Add commands to set the start position of the sprite as x = -150 and y = -150

12. Making the pen appear and disappear
Add in show and hide at the beginning and end of the script

13. Over to you…..
Now that you have learned the basic of pen programming you can experiment with your own ideas and designs
