Using geoboards, computer programs, and hands-on manipulative materials, elementary schoolers engage in a study of two and three-dimensional geometric shapes. This lesson is chock full of good teaching ideas on the subject, and the...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Research various types of bridge designs. Your class will be asked to consider what it would be like without bridges while learning about how they work. They will construct a model bridge based on given parameters. They then calculate...

Children who are blind need to constantly be engaged in building conceptual understandings of the world around them. This activity will help them grasp the concept of shape, identify shapes, and consider shapes as they are used to...

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

Students explore ocean ecosystems. In this cross curriculum art and oceans lesson, students create a collage featuring three-finger algae using sand paper, tissue paper, and construction paper.

Students make masks. In this African art lesson, students review background information about African art and the use of masks. Students use geometric shapes and other designs to create their masks.

Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

Students use a monochromatic palate, select shades and tints for a selected hue, or select complimentary or analogous colors for a quilt design. They design quilt squares using basic geometric shapes, repetition, balance, and proportion.

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Imagine making square envelopes out of circles. Yep, all you need are paper, scissors, a compass, and some glue. Kids explore the possibilities of geometric shapes with this activity.

This two-part reading comprehension exercise asks kids to read a short passage about cubes, rectangular prisms, spheres and pyramids, and then to respond to a series of questions about the article.

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this instructional activity. They make a set of tangrams and use them to...

Rays and angles and Star Wars? It sounds strange, but it's actually a fun game to help fourth graders get good at measuring and identifying angles and rays with a protractor. Each pair of children chooses which Star Wars character they'd...

After walking in a nearby neighborhood, have your class create this amazing city street pop-up. They study the facades of the buildings they see, focusing on geometric line, shape, and architecture. They then draw, cut, and create a city...

Students create a Philippine banig mat. As part of designing and creating the mat, the class is introduced to the tropical rain forest of the Philippines and how the environment impacts the lives of the people. Individuals also discover...

Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Challenge your classes to design and market a new product. Collaborative groups use geometry skills to create packaging for their products. Finally, they plan a marketing strategy to present to a marketing specialist.

Students design recreational equipment for a community. In this architecture lesson, students work in pairs to design the equipment. Students select materials and begin designing. Students assess themselves with a pre-made rubric.

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

Students create a car using physics. In this forces and motion lesson, students create a car and test which changes in design change the performance of the car. Students complete a graphic organizer with the different changes...
