Students investigate nets as they relate to volume and area. For this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Students create three dimensional shapes using concept maps. In this geometry instructional activity, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students investigate orthographic drawings. For this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

Third graders describe 2D and 3D shapes. In this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have in...

Twelfth graders examine different dimensions and units which go with a particular dimension. They explore the concept of linear measurement versus area. Students estimate area of 3-D objects. They practice converting from one unit of...
