This article for students gives some instructions about how to make some different braids.
Turn through bigger angles and draw stars with Logo.
You could use just coloured pencils and paper to create this design, but it will be more eye-catching if you can get hold of hammer, nails and string.
Arrange your fences to make the largest rectangular space you can. Try with four fences, then five, then six etc.
Write a Logo program, putting in variables, and see the effect when you change the variables.
A jigsaw where pieces only go together if the fractions are equivalent.
Can you puzzle out what sequences these Logo programs will give? Then write your own Logo programs to generate sequences.
What happens when a procedure calls itself?
Have you noticed that triangles are used in manmade structures? Perhaps there is a good reason for this? 'Test a Triangle' and see how rigid triangles are.
