Build boxes using unit cubes to compare surface area and volume. The group performs multiple experiments to determine properties of volume, such as if it makes a difference which order the dimensions are multiplied in. Extensive...

Learners 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...

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...

Young scholars explore space shapes learning about edges, corners, and faces. They enjoy shape soup as a culminating activity.

Middle schoolers create a mobile of boxes and cubes that they made in a previous lesson that can be accessed from this page. They design the mobile using method that an engineer would use to balance the items based on surface areas and...

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.

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...

Young scholars identify three-dimensional forms in various buildings and construct three-dimensional paper forms.

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 read The Greedy Triangle and discuss geometric solids. In this geometry lesson plan, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

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...

Elementary learners explore coin mint dates. First, they listen to the book Alexander Who Used to be Rich Last Sunday by Judith Viorst. They then sort a collection of coins according to their mint date and put them in order from oldest...

Students build replicas about nature and sports. In this geometry lesson plan, students build 3D replicas of nature and sports objects in teams.

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Third graders construct and use vocabulary flipbooks to draw and describe three-dimensional figures. They utilize worksheets and access websites imbedded in this plan which help them construct their books.

Students explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups,...

Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Pupils investigate measurement through the use of literature through this series of lessons.
