Monday - Friday, July 19-23, 2004
This week has been spent working on our working group projects. What follows is what the projects are, who is working on them, and a brief summary of what they are doing.
This group is producing materials and activities that require Geometer's Sketchpad. They will begin with activities for middle school students that introduce them to Sketchpad. The activities will revolve around string art. The activities for 9th and 10th graders will involve star polygons and the patterns with those.
This group is building upon the work we did with polyominos in week 1. Marcia and Stephanie are focusing on Geometry activities with polyominos (and in particular, pentominos). Their activities involve perimeter and area activities, Java applet games that focus on spatial skills and congruence, and similariy and congruence. Nick is focusing on taking the patterns in the polyominos and using them in algebra.
Bill and Jennifer are exploring the mathematics behind those stereographic pictures. They are the pictures that you stare at for a while and a hidden 3-dimensional picture appears. They are also working on a method for producing simple stereographic images with students by making a stereographic image of a Zometool shape.
