<br>This is one of the best sheets ever for teaching maths (designed by Barry Newell):<br><ul><li>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</li>
<li>the sheet includes both simple and complex shapes, increasing in order of complexity, there is a challenge there for everyone</li><li>many of the more complex shapes are made up of combinations of the simpler shapes</li>
