Thing # ?

Did something cool in my class. Took pictures of the students balancing triangles on pencils to find the center of gravity or Centroid. Transfered the pictures to my laptop and projected them on the wall the following day. The students loved seeing themselves and we used it as a review and opener for Geometer Sketchpad and constructing 4 points of concurrency. Once again the overhead projector and easy use of the laptop make life easy. We were able to access web site Dr. Math again to look at Napoleans theorem and Morley's theorem. This is cool stuff.

What a powerful, reinforcing thing - photos of the kids themselves, in the midst of their activity. Who doesn't like to see his or her own face?! I'm still amazed at the things that technological advances allow us to do. -Janet
