Now they have five Shape Makers left to identify. They begin to study in more detail the corner aids on the screen and watch as they manipulate the Maker to see the angles and side length measurements change. This helps them identify properties, and thus define the rest of the Makers. The students quickly learn to move fluently through the various computer screens to find information that will help them determine the identity of the Makers. They go back to their notes, they check the conjectures students have posted on our chart paper, and they reason.
Students develop powerful geometric reasoning as they progress through the unit.
