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.
Curated OER
Introduction to Polyhedra
Learners investigate Euler's Formula. In this geometry instructional activity, students perform an inductive activity of Euler's Formula using nets to identify a variety of prism, pyramids, cylinders, and cones.
Curated OER
Sketching Spheres
Pupils investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.
Curated OER
Sketching Pyramids
Students sketch and identify properties of pyramids. In this geometry lesson, students create nets to identify three dimensional shapes. They sketch cones, prisms and pyramids.
Curated OER
Shapes are Everywhere
Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
Curated OER
Classifying Pyramids
Students study pyramids. In this prisms lesson, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.
