[IAEP] 40 maths shapes challenges

[Costello, Rob R]

Hi Maria 
 
like the logo approach....
 
loop 360
  forward 1
   right 1 
 
is a simple way to approximate a circle
 
could also use scratch's trig functions to draw a circle, but i guess the first is more what the bodily syntonic thing is about,,,how does it feel to walk around a circle
 
cheers
 
rob

Circle is one of the hardest in Scratch. Unless I am missing a command.

	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
