Roberto, Here are some examples of teaching Mathematics with Etoys: <ol><li>Fractions: </li><ol><li><a href="http://squeakland.org/showcase/project.jsp?id=7673" target="_blank">Fraction Tools</a> - Use virtual Cuisenaire Rods to help kids obtain a better understanding of fractions and units of measure.</li> <li><a href="http://squeakland.org/showcase/project.jsp?id=7372" target="_blank">Fractions of a Circle</a> - A Fraction Game</li></ol><li>Area: </li><ol><li><a href="http://squeakland.org/showcase/project.jsp?id=7744" target="_blank">Area Geo Boards</a> - Exercises for learning about squares and areas.</li> </ol><li>Pythagorean Theorem:</li><ol> <li>Demonstration of Pythagorean Theorem Proof: Check Video first: <a href="http://www.youtube.com/watch?v=YIGCdOtfd7E" target="_blank">video</a> The <a href="http://squeakland.org/showcase/project.jsp?id=9486" target="_blank">project</a> shows the final result, could be modified to challenge kids to prove it. </li></ol><li>Geometry</li><ol><li><a href="http://squeakland.org/showcase/project.jsp?id=7751" target="_blank">Shapes</a> - This project introduces kids to Geometric Shapes, terminology and comparing and contrasting different shapes. </li> <li><a href="http://www.squeakland.org/showcase/project.jsp?id=9444" target="_blank">Creating Polygons</a> - Based upon <a href="http://billkerr2.blogspot.com/2009/08/40-maths-shapes-challenges.html" target="_blank">40 Math Shapes</a> designed by Barry Newell. This challenge could also be done in Turtle Art and Scratch, but it demonstrates one of the advantages of Etoys over Scratch (haven't used Turtle Art, so can't comment). In that you can drag scripting tiles onto the Playfield in Etoys. This allows you to focus the students attention on the problem you want them to solve rather than having them look through all the tiles to figure out what to use. The Etoys Challenges are an excellent example of this. One of the challenges of learning Scratch and Etoys is discovering all the scripting tiles. This is easier in Scratch as they are always visible, in Etoys you have to open an Objects Viewer, not hard, but an extra step. NOTE: In this project all the scripting tiles you will need aren't always visible (it is a work in progress I believe, so it may have changed by now). </li></ol></ol>What grades and subject matter will you be teaching? <div class="gmail_quote">On Sun, Feb 28, 2010 at 1:58 PM, roberto <<a href="mailto:roberto03@gmail.com" target="_blank">roberto03@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> >>> >>> On Wed, Feb 24, 2010 at 2:43 PM, Simon Schampijer >>> >>> <<a href="mailto:simon@schampijer.de" target="_blank">simon@schampijer.de</a>> >>> >>> wrote: >>> >>>> >>> >>>> Hi, >>> >>>> >>> >>>> I am teaching on a regular basis in the Planetarium pilot in Berlin, >>> >>>> Germany [1].
