Students identify two and three dimensional shapes and use appropriate geometric vocabulary to write a description of the figure by taking pictures of geometric figures in their own environment.

First graders examine and discuss a bronze statue by Degas, and identify the differences between painting and sculpture. They create three-dimensional figures using a variety of textures.

Fifth and sixth graders work alone or in pairs to determine the volume of paper boxes of various dimensions. Pupils write ratios of dimensions and volumes.

Students calculate the surface area of prisms. For this geometry lesson, students investigate the properties of prisms and analyze ways to calculate the are of a rectangular prism. They derive the formula for surface area.

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

Third graders consider space and the techniques artists use to create three-dimensionality within a painting or drawing. They examine works by Millet, Bruegel and Demuth and then create original drawings that explore the effects of...

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...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Young scholars identify and use appropriate formulas to find surface areas of solid figures, practice using formula sheet to solve textbook problems, construct solid figures of given surface area using TABS+ software program, and use...

Learners describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist...

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

Students sketch and identify properties of pyramids. In this geometry lesson, students create nets to identify three dimensional shapes. They sketch cones, prisms and pyramids.

Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.

Students calculate the surface area of different prisms. In this geometry lesson plan, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

Students identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.

Middle schoolers work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their...

Transform your lesson on transformations. Learners use given congruent triangles and tracing paper to determine the single transformation that carries one to the other. The concept is extended to combinations of transformations to...

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.
