In this geometry worksheet, students draw 6 different shapes as requested by 6 specific directives in the circles provided. Students draw 2D and 3D shapes.

Third graders describe 2D and 3D shapes. For this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have...

Primary geometers create a picture using tangrams. In this geometry lesson plan, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram...

Young scholars solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities...

In this three- and two- dimensional geometry learning exercise, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

In this ratios for area and volume worksheet, students solve problems where they find the ratios for problems of shapes dealing with area and volume. Students complete 4 problems.

Tenth graders plot points on a coordinate plane. In this geometry lesson, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

Students will learn and reinforce skills for measuring perimeter and area of 2D shapes and measuring surface area and volume of 3D shapes.

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

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

My first graders have been studying the defining attributes of 2D shapes. They are going to love using toothpicks and marshmallows to present their knowledge of 2D and create 3D shapes.

This resource allows users to test their geometry knowledge.

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

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.

Practice your 3D visualization skills by rotating 2D shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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

Cross-sections are one way that two-dimensional objects are connected to three-dimensional objects.

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 video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

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...

Practice your knowledge of all possible cross-sections of common 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
