High schoolers identify the volume of cones and pyramids. In this geometry activity, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Students investigate properties of circles. In this geometry activity, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Shape shifters examine and experiment with pattern shapes.  In this geometry lesson, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed inside a hexagon.

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Learners participate in a two-week real-life math unit. In pairs, they calculate salaries, taxes, and a budget, plan a vacation, buy insurance, make a will, and design a room. They conduct Internet research to plan the vacation, and...

Second graders culminate their study of shapes by describing the shapes using the proper mathematical descriptors.

In this shape recognition worksheet, students study the various 3 dimensional figures and identify each one. Students label the 10 figures.

Second graders explore geometric shapes. In this lesson about geometry, 2nd graders create their own vest using geometric shapes. Students work with a partner and fit their partner for the vest they design. Students understand geometric...

Students identify and name different geometrical shapes. In this math instructional activity, students distinguish odd from even numbers. They describe the properties of 2 and 3 dimensional objects.

Students describe, identify and compare two-dimensional figures. They also name and demonstrate the relative position of objects using directional words. They sort and compare two-dimensional figures and three-dimensional objects...

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

First graders combine different shapes to create an image.  In this geometry lesson plan, 1st graders utilize squares, circles, rectangles, triangles, and arc to draw a picture.  Students share their creation with their class...

Students explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Students collaborate in graphing additional functions.

Apply the Pythagorean Theorem in three-dimensional shapes. Young mathematicians watch a video that takes them through several examples of using the Pythagorean Theorem to solve problems involving lengths in three-dimensional figures. A...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Students examine problem solving techniques when working on spatial problems. They discover how models, sketches, and drawings can be used to understand on something works. They design a model of a bridge using given dimensions and...

In this math vocabulary worksheet, students match the math vocabulary definitions to the letter shapes. Students write in 8 words in the letter shapes.

In this mathematics worksheet, 1st graders identify which object in an illustration has a flat side the same shape as the box shown. Then they look at other shapes and identify the ones with a flat side, if any.

Students use tangrams, student literature, and Websites to explore shapes.

In this math vocabulary instructional activity, students complete 15 multiple choice problems, choosing the correct definition for a set of math terms. A reference web site is included for additional activities. 

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