Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry instructional activity, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.
Curated OER
Tessellating Tiles
Second graders Make, name and describe, using their own language and the language of geometry, everyday shapes and objects. They create and talk about geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
Curated OER
Infinity
Students engage in a lesson plan that is concerned with the concept of infinity as defined in a series by geometry. The lesson plan integrates the use of philosophy to help them comprehend how infinity can possibly mean while...
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
The X-33 and the X-38
Learners explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.
