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. 

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

Dominoes, polyominoes, tetrominoes, and pentominoes are the subject of this interesting math activity designed for middle schoolers. Pupils cut out shapes that are embedded in a worksheet in the plan, and experiment with them by...

Use coordinate grid paper to plot points and identify shapes that are already plotted on the paper by saying their coordinates. Pupils also measure the distance between points and play the game Battleship. There are several web links and...

Students investigate topology. In this Applied Science lesson students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.

Congruence and similarity apply to functions as well as polygons. Learners examine the effects of transformations on the shape of parabolas. They determine the transformation(s) that produce similar and congruent functions.

Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

The class explores Ukrainian motifs, the scratchboard technique, and two-dimensional art. They design and produce a Ukrainian style egg with tagboard, crayon, tempera paint, and a stylus. Ukrainian egg designs are similar to those used...

In need of math vocabulary cards? Use a set of 66 vocabulary cards with topics focused mostly on geometry terms. Each sheet has two cards on it. The top half has the word printed in bold text, while the bottom half has the card with...

What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

Who needs a pie-eating contest when you have a pi-ology game! Celebrate March 14th with a fun board game about pi and other geometric concepts. As learners answer questions about geometry, they move around the board to collect...

In this pattern completion activity, students observe groups of six patterns and add the final two patterns. Students complete five sets of patterns.

Students are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...

Leading the students to draw a representation of ellipses of planets, this handout will help understanding the planet movement around the sun.  There are ten questions about the analysis of those orbits and a conclusino specifically...

Examine repeating and intricate patterns with a study of M.C. Escher and a related art activity. Pupils view and discuss the artwork before creating their own tessellating patterns. Step-by-step instructions for creating a template are...

Group work and participation is used to perform a specified translation or reflection. In this geometrical translation lesson, small groups of pupils are each given a shape to plot on a coordinate grid. Each shape is then translated or...

Maximize a profit with an understanding of geometric dimension. A real-world task challenges learners to design a pattern using three different brick shapes. The bricks are dedicated with a different donation for each shape, so part of...

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the instructional activity. In part two, students use geoboards to construct polygons, look for patterns, and find a...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Third graders discover elements in visual art. In this visual art lesson, 3rd graders explore the use of line, shape, and color in visual art. After reviewing works of art, students create unique art pieces. Technology resources provided.

Fifth graders solve problems while examining a variety of isosceles triangles.  In this isosceles triangle lesson, 5th graders examine shapes to find their characteristics.  Students pay particular attention to the...

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...
