Software: MicroWorlds
- Open the program and click in the
Command Centre.
- Type a simple sequence including a
forward and turn instruction. eg fd 40 rt 56
- Repeat the sequence until the lines
meet or cross. Did the repeated sequence create a regular
shape?
- Try a different sequences. Discuss
the feature which will change the final shape (the
angle). Brainstorm angles which may may create a regular
shape. 30, 45, 60, 72, 90 etc
- Try repeating a sequence of commands
with the suggested angle sizes. eg fd 40 rt 45
- How many times was the procedure
repeated to complete a regular shape? Write a procedure
using REPEAT.
- Change the angle sizes and the number
of repeats. What is the relationship? ( 360 = 6x60, 8x45
etc)
- For an extension activity, the use of
a variable can be introduced.
