Seventh graders investigate the mathematical concept of a sector. They apply the concept to an example problem and then move into a more complex application. They find the area of the side of a cone. This is done as students calculate...

Seventh graders solve word problems involving real world situation. In this geometry instructional activity, 7th graders solve problems related to volume. They apply the formulas taught in geometry.

Students observe solids and identify parts that make up the surface area. In this geometry lesson, students calculate the surface are of solids and cones. They find polygons and solids in the real world.

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

In this formula worksheet, students complete a graphic organizer, answering the questions relating to: understand, plan, solve, look back. Students solve 2 problems. Houghton Mifflin test is referenced.

What is a pyramid? Find a definition, example images, and formulas for finding the volume and surface area of a pyramid if given base and height measurements. Includes a very brief look at a pyramid in Egypt and its measurements.
