Check out GeoGebra OER community. There will be a US conference this year, and the online resources and groups are good, too. <br><br>A lot of my students appreciate geometry through the following lenses:<br>- Origami<br>- Computer graphics, especially programming cool visuals for games<br>

- Escher, Dali, and other &quot;surreal&quot; space transformations - we are doing a lot of it in our &quot;Alice in Wonderland&quot; class, hehe.<br><br>We watch videos a lot, too.<br>Mobius transformation:<br><a href="http://www.youtube.com/watch?v=JX3VmDgiFnY">http://www.youtube.com/watch?v=JX3VmDgiFnY</a><br>

I&#39;m teaching high school math to homeschoolers and I&#39;m looking for how to make<br>
geometry year meaningful.<br>
<br>
I&#39;m having a &quot;crisis of confidence&quot; because from my viewpoint, algebra was 10x<br>
more useful for future math and science work.<br>
<br>
The only thing I can remember that was useful from geometry was a few volume<br>
and area formulas.  That can justify maybe a month but not a whole YEAR of<br>
geometry!?!?<br>
<br>
cs<br>
<br>
P.S. Yes yes I know that geometry is meant to teach logical reasoning.  Maybe<br>
one can get that from chess, debate club and other activities as well if<br>
not better?  People also say geometry is where you learn proofs.  Couldn&#39;t<br>
proofs be just as easily emphasized in all the other math classes?<br>
