A Cone and Its Net

For Teachers 6th - 10th
Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

More Prisms/Nets

For Teachers 9th - 11th
Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Investigating Nets and Polyhedra

For Teachers 5th
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Sketching Cylinders

For Teachers 9th - 11th
Students create nets of cylinders. In this geometry lesson, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.

Mandalas, Polygons and Symmetry

For Teachers 9th - 11th
Students create a geometric pattern using mandalas, polygons and symmetry. In this geometry lesson, students analyze the mathematics involved in making the mandalas, including the shapes and symmetry. Students create their own mandalas...

Polydron Fun

For Teachers 9th - 11th
Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Connecting Measurement

For Teachers 7th - 8th
Students participate in activities the connect measurement to geometry, statistics, estimation, and the real world. They collect measurements from their elbow to the tip of their middle finger and make a box plot of the data as well as...

Surface Area of Prisms

For Teachers 9th - 11th
Students calculate the surface area of different prisms. In this geometry lesson, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

Getting Familiar with Fractals

For Teachers 9th - 12th
Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Guess My Shape

For Teachers Pre-K - 1st
Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Classifying Pyramids

For Teachers 6th - 7th
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.
