Eighth graders find the length of the third side of a right triangle.

Ninth graders calculate the distance between two points.

Young scholars randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.

Students manipulate a variety of materials and computer applets in order to explore area and the units used to measure it.

Students investigate an attic or basement to "discover" family artifacts. They develop a grid map using string, create a naming system for the grid, and analyze items of interest.
