[IAEP] 40 maths shapes challenges

[Costello, Rob R]

yes,  i had success using that sheet as well Bill ...

here's a quick demo i did of scratch in action - emerged out of lesson  - i talked through a simple square for a couple of minutes; asked the students how i would make it triangle -  a year 8 girl suggested the approach; which we then generalised to any number of sides

students were off trying to build the shapes, or coming up with new ones ...some seem to find their niche with this

Forty shapes to make in Scratch <http://scratch.mit.edu/> or some other
version of logo, such as Turtle
Art<http://wiki.sugarlabs.org/go/Activities/Turtle_Art>.
It's hard to see the thumbnail but click on it for a larger view.

This is one of the best sheets ever for teaching maths (designed by Barry
Newell):

   - the logo turtle or scratch cat acts as a transitional object between
   the concrete maths shape and the abstraction of the script that makes the
   shape
   - the sheet includes both simple and complex shapes, increasing in order
   of complexity, there is a challenge there for everyone
   - many of the more complex shapes are made up of combinations of the
   simpler shapes
