This lesson offers an interesting, hands-on experience for middle school students studying cylinders. Students will create cylinders, and measure and compare their volumes.

For this lesson, students will explore self-portraiture by looking at classical portrait paintings, such as Diego Velazquez's La Infanta Margarita or Raphael's Portrait of Baldassare Castiglione. A close look at these works reveals...

Introduces the concept of polyhedrons by learning the definition, types, and where they are found. Check-out the solved examples for better understanding and try your hand at solving a few interactive questions at the end of the page.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on identifying and naming three dimensional figures.

[Free Registration/Login Required] This is a formative assessment task where students are asked to use geometric solids to model each of four tent shapes on a worksheet and use mathematical language to describe them. Samples of student...

Students will tell if a shape is 2-dimensional or 3-dimensional.

In this enrichment game, the nets for nine solids are displayed. The twist is that each net has been cut into two pieces. The challenge is find the pieces that go together.

On this interactive website students practice various math skills using a real life scenario. Those skills include identifying 3D objects, identifying the similarities and differences in prisms and pyramids, and drawing 3D shapes such as...

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.

This task asks students to compare the volumes of three vases that are different shapes - a cylinder, a cone, and a sphere - as well as one with a combination of shapes. They are then asked to create a vase with composite shapes, find...

A geodesic dome is constructed using newspaper for this activity. The activity is accompanied by a lesson plan, and a link to a 'Shapes Lab' where you can see through animation the strength of various shapes for construction.

Use this tool to see animated models of over 100 different types of polyhedra. There are five options for how they appear, and you can also see the net, 'explode' the solid so that the faces are separated, or drag it to rotate it...

The resource consists of a tool to investigate the area of a variety of shapes. It could also be useful when calculating the surface area of each face of a 3D solid, and then adding them together.

Explore surface areas and nets with 2D and 3D shapes.

Percy the Penguin needs to clean up his 3D shaped toys. Can you help him?

Brain binders are great teacher sources for problem solving and critical thinking with geometry. Students fold sheets of paper to create solid colors on each side. Various levels are included starting with two folds through five folds.

Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box...

Use this interactive tool to explore prisms. Change the height and the shape of the base to see how these affect the prism. There are also several additional options, e.g., making it oblique or transparent. Properties of a prism are...

Practice matching 2D nets to the 3D shapes the fold up into. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this task, 8th graders are presented with a drawing of three glasses of different shapes and their measurements. They are asked to make several calculations that require the application of the Pythagorean Theorem and volume formulas....

This tutorial will show you how using formulas can help you solve problems. Include formulas for various geometric shapes and steps showing how to use them.

In this lesson, students use movement and the creation of human structures to help them understand angles, plane shapes, and geometric solids.

The students will find the area of each two dimensional figure on a net of a rectangular prism. In groups, students will cut out the net and create a rectangular prism. Groups will then discuss how to find the lateral area and the total...

On this interactive website students practice various math skills using a real life scenario at a toy store. Those skills include describing the features of pyramids, prisms, cones, cylinders and spheres.
