Students investigate nets as they relate to volume and area. For 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...

Students find the volume of rectangular prisms.  In this volume activity, students use a formula to find the volume of rectangular prisms.  They discuss the definition of volume and draw rectangular prisms.  Students...

Students explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

In this math activity, students practice their skills in constructing reflections of shapes that are on a grid. This activity has 13 problems for the students to solve, and includes an answer sheet.

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Fourth graders find the volume of solids. In groups, 4th graders use spinners to determine the dimensions of solids. They construct the shapes, creating a model of the figure Students count the cubes in the model to determine the...

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

In this spatial relations worksheet, students solve three-dimensional problems. They find the total number of triangles in a given figure, the number of line segments that endpoints and use integer points to solve two problems. This...

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

[Free Registration/Login Required] This flipchart discusses plane figures and solid figures.

Students read the clues to determine the shape the clues are describing. If they choose the correct shape a smiley face appears.

In this lesson, students will identify 2- and 3-dimensional shapes as well as create shape drawings and sculptures. Teacher materials are available.

A guide to support parents as they work with their students with two-dimensional and three-dimensional shapes.

An interactive game to find number of edges, surfaces and vertices of different geometric shapes.

[Free Registration/Login Required] This flipchart explains 2-D and 3-D shapes.

In this lesson, students will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

This site includes an interactive math tool to create drawings on isometric dot paper. You can draw figures using edges, faces, or cubes. Rotate and color your drawings, and view them in 3D or 2D.

In 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...

[Free Registration/Login Required] Students will learn the 6 solid figures and characteristics, including face, edge, and vertices. Students will learn the plane figures when looking at the solid figures. Students will then take a 10...

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

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.

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...
