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

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

Learnersinvestigate three-dimensional shapes. In this geometry lesson, pupils calculate the volume of cylinders using the given dimensions. They create a formula base don observation before using the real formula.

Students recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of students will extend the study of polygons to...

Learners analyze the black-figure painting style of ancient Greece and its influence on Neoclassical artists during the 18th century, as seen in drawing, painting and silhouettes, or shadow portraits. In this ancient art...

Third graders describe 2D and 3D shapes. In this geometry activity, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have...

For this 3 dimensional figures worksheet, students study the 10 3-dimensional figures. Students identify and label each of the 10 figures.

Elementary school learners investigate the attributes of a square. They discover that squares are polygons and examine squares found in everyday life. They concentrate on connecting the word, square, with the shape. As an...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

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.

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

Students create different shapes on grid paper.  For this two-dimensional geometry lesson, students take turns outlining a shape made of six squares on the graph paper.  They identify all shapes they see once everyone has had a...

Students practice geometry skills. In this geometry lesson plan, students find the surface area of cubes and prisms, identify shapes on solids, and distinguish between 2-dimensional objects and solids.

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

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...

Have your class participate in a variety of sports and craft activities using this resource. With sports as the theme, learners work on art projects. Students create soccer ball prints, a three dimensional football, and a sports collage.

Learners photograph shapes around their school and create a shape movie.  In this shape hunting lesson, students recognize shapes in a shape hunt.  Learners can identify the shapes recorded by others in the class.

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

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, 1st graders utilize squares, circles, rectangles, triangles, and arc to draw a picture.  Students share their creation with their class...

High schoolers, through investigation facilitated by dynamic geometry software, determine geometric properties and relationships involving two-dimensional shapes, and apply the results to solving problems.

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Math scholars study conics and how they are used today. In this mathematical lesson, pupils construct and slice cones after viewing a demonstration.
