Here are some star challenges. In each case they are created by rotating repeated shapes. You may find it useful to print off this page for reference, or perhaps so that you can trace over the lines to work out what the unit of repeat is. 

Challenge number 1

Can you use TWILGO to draw the Star-square?

 

 

 

Challenge number 2

Just four different procedures were used to produce the design below.            

How would you set about the task of deciding what to do?

How would you replicate this design?

How systematic were you?

Can you use even fewer procedures? 

 

 

Challenge number 3

Here's another - this time there are stars within a star. Can you work out what the unit of repeat is? 

Is there only one possible answer?
