An outstanding activity on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed...

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Students create a geometric pattern using mandalas, polygons and symmetry. For this geometry lesson, students analyze the mathematics involved in making the mandalas, including the shapes and symmetry. Students create their own mandalas...

Students classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

High schoolers identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.

Learners identify the different parts of a right triangle. In this geometry lesson plan, students use the Pythagorean Theorem to identify missing sides and angles of a right triangle. They work with irrational and rational roots.

Fourth graders find the volume of cubes and cylinders. To determine volume, they fill large cubes with centimeter cubes. They discuss the formula used to find the volume of a cube. Students explore why the solution to the volume of a...

Pupils identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...
