In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.

Students explore geometric solids. In this geometry instructional activity, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric...

Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...

High schoolers are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

Young scholars enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Students 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...

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry lesson, 3rd graders create their own building designs and identify the geometric shapes that...

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Students discover the characteristics of polyhedra. Through hands-on activities and interactive videos, students investigate and retrieve information on polyhedra and crystal structures. Students study angles and symmetry. They...

Middle schoolers identify lines of symmetry.  For this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Middle schoolers cut shapes out of...

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 build a scaled model of the solar system. In this space science lesson, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

Students examine and discuss a sculpture by the artist Jin Soo Kim. They explore and identify basic sculpture techniques, and create a sculpture using found objects, plaster, and cardboard.
