Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

In this geometry worksheet, students cut out a net of a cone by following along the dotted lines as indicated by the scissors icon. They fold the figure to form a three-dimensional cone which they tape together. There are no directions...

Explore finding the surface area of composite figures. Building on the previous lessons in the 29-part series, the 24th installment examines the surface area of three-dimensional solids. The focus is on decomposing composite figures and...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Third graders evaluate the attributes of cones. In this space shapes lesson, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.

In this 2 and 3 dimensional figures worksheet, students determine whether given shapes are regular or irregular. A reference web site is given for additional activities.

In this area worksheet students read story problems, determine the necessary information to solve the problem. They find the amount of material needed to construct three-dimensional figures. Students determine the greatest and least area...

In this volume worksheet, students recognize three-dimensional figures, identify the proper volume formula, and then solve the equation by inserting information from a diagram into the formula. Students solve six equations.

In this solid figures worksheet, students use the figures for the cube, pyramid, and rectangular prism to answer the six questions about the characteristics of solid figures.

In this 3D figure instructional activity, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.

Geometry could be called the study of figures. An overview of the figures found in a typical geometry course contains a study of different triangles, quadrilaterals, and regular polygons. 

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

A collection of two lessons, kindergartners will identify two-dimensional shapes in solid shapes. They will develop basic knowledge of the components that make up a sphere, rectangular prism, pyramid, cylinder, cone, and cube. Young...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

When painting a barn you have to calculate surface area, and that is exactly what this resource is about. Not only will your future home owners calculate the surface area, but also the cost. It is a real-life problem that every that...

Hook your charges on how to solve a real-world art problem with mathematics by showing works of Christo. You can find eye-catching images on the Christo and Jeanne Claude webpage. Here, math learners help Jean Claude and Christo prepare...

Examine patterns of figures composed of six-squares and predict which of the twenty presented could be folded to make a cube. They then fold large-scale patterns of these figures to confirm their hunches.

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

Name that shape! Your math class identifies cubes and other three-dimensional products. They practice calculating the volume of cubes and identify cubes around them in the classroom. Worksheets and directions are provided.

High schoolers identify various geometric shapes. Apply the given formulas to determine the volume of these shapes. Design their own container to conform to specifications provided. Use their knowledge of volume formulas and shapes to...

Middle schoolers explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and...

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

Sixth graders view a video of tessellating an egg shape. They focus upon the problem solving strategies used and how tessellation geometry was used to construct the three dimensional figure. They create their own tiling patterns.
