I am so impressed with the extra-credit projects I have received. For the first time I some of my students have created very helpful, not to mention attractive, book marks. Be sure to take a look. I hope that creating them helped them to "remember" important Algebra/Geometry facts. I would really like to hold on to them, but I feel the creators might like them back so that they can use them.
Here is Callie's.
Here is Jocelyn's.
I also received a very informative paper on Archimedes. I am afraid that the author does not want her work published. It was an excellent read, by the way.
Finally, not every endeavor ends the way it should. Richlan worked long and hard to create a slide-together. Here is a picture right after she threw in the towel. I love her willingness to try so hard, and I hate it that it didn't "all come together." She still earned extra-credit points, not that she really needs them.
