Around the World With Geometry
Learners identify shapes, create shapes, and make a pyramid, a drum, and a sail using their shapes. In this shapes lesson plan, students also identify plane and space shapes.
Curated OER
Shape All Around
Students investigate solid shapes. In this geometry lesson, students take pictures of solid shapes and classify their pictures according to the vocabulary terms: edge, face and vertex. Students present their findings to the class.
Curated OER
Surface Area
In this geometry instructional activity, 10th graders define surface area, net and lateral face. They calculate the surface areas of cones, prisms and cubes. There are 9 surface area questions.
