Students identify the parts of three dimensional objects. In this geometry lesson plan, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

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.

Pupils create a rectangular garden using paper and tiles. In this geometry lesson plan, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the rectangles...

Young scholars create three dimensional shapes using concept maps. In this geometry activity, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Pupils examine the idea of "regularity" as it pertains to geometry.  For this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Students explore geometric concepts by working with Tangram Puzzles. For this Tangram challenge lesson, students use problem-solving tasks that involve physical manipulatives. Students select a picture and use all seven pieces...

Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.

Sixth graders inspect prime and composite numbers. Using graph paper, they draw as many different shaped rectangles as possible. They use the dimensions of the rectangles to discuss prime and composite numbers. Students create a chart...
