Getting Into Shapes: Identifying and Describing Two-Dimensional Shapes
Young scholars examine their classroom to find examples of various types of shapes. After identifying and describing the various shapes, they draw as many as they can on a piece of paper. They organize them into an image based on their...

Sketch Up
Students estimate and measure exact. In this geometry instructional activity, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.

The Trappings of Trapezoids
Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

The Trapping of Trapezoids
This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles.

Volume and Surface Area
Students explore volume and surface area. In this math lesson, students fill boxes with cubes to identify the volume of the boxes. Students discuss area.
