From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

Young scholars discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs...

Students prepare to take the GED by reviewing basic math concepts. In this geometry instructional activity, students review vocabularies such as formula, perimeter, circumference and other important geometric terms. They convert between...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Students model three-dimensional objects using cubes. In this geometry lesson, students calculate the volume and derived the amount mathematically. They use different objects to create two and three-dimensional objects.

Students investigate geo-profiling.  In this secondary mathematics lesson, students use geo-profiling to determine the most probable location of a criminal.  Students find the centroid of a polygon where the vertices represent...

Students create two prisms out of the same paper. They calcuate the number of centimeter cubes needed to fill each prism. They discover the concept of volume.
