Geometers construct a mobile or ornament using nets of three-dimensional polyhedrons. Not only do they need to compute the volume and surface area of each figure, they also earn points for creativity, neatness, and more!

Students explore geometry by participating in a shape identification activity. For this figure dimensions lesson, students identify the difference between 2 and 3 dimensional shapes by their vertices and faces. Students examine blocks in...

In this three dimensional geometry crossword, learners explore terminology in fifteen crossword problems.  A word bank and solutions are provided.

Students hone in on their skills at reading diagrams.  In this dimensional lesson students collect information on the functions of organs then figure out how all the parts work together. 

Students solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Building a six-sided number cube has never been so easy. Just cut out the figure on the solid lines, fold on the dotted lines, connect the sides together using glue or tape, and there you have it!

Calculate one hypotenuse then repeat. The resource provides a variety of ways for finding the length of the diagonal in a prism. Using the Pythagorean Theorem, pupils find a variety of distances in 3-D figures. The distances range from...

Geometric shapes are used in math and in art. Learners discuss the various names, dimensions, and attributes of geometric shapes, then apply that knowledge to design a vase. They use 3-D shapes to make a cubist-style vase out of clay.

In this three-dimensional shapes worksheet, 6th graders identify and complete 4 different questions that include various types of three-dimensional shapes. First, they identify the shape illustrated as it relates to a cube. Then,...

Use a Platonic solids worksheet to record the number of faces, edges, and vertices of five polyhedra whose faces, edges, and vertices are all identical. For each figure, learners write a proof of Euler's formula (F+V=E+2). They create a...

Third graders draw shapes that are congruent. In this congruency instructional activity, 3rd graders use grid paper to draw letters and figures and their congruent partners. They complete a worksheet while working in a whole class...

Use this volume of solids lesson to have learners find the surface area and volume of cylinders, pyramids, and prisms. They place cubes inside three-dimensional figures to determine the volume. Worksheets and answers are provided.

Some of the best practice with shape identification comes from drawing the figures first-hand. Young geometers draw nine two-dimensional shapes: rectangle, circle, square, pentagon, hexagon, octagon, triangle with three equal sides,...

Inside each of these two-dimensional shapes, scholars identify the figure by writing its name. There is a word bank for them to work from, but some shape names are used multiple times. There are six identifiers they use: pentagon,...

Students identify and classify solid geometric figures. In this geometry lesson plan, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on each figure.

See how art can communicate the idea of working together with your class. They will view art and describe space, color, shape, and lines in art. Then they will overlap in their art to show a sense of space. In the end, they will be able...

Boost lemonade sales by using the perfect container. For a given volume, future entrepreneurs design a container that will have the least surface area and by extension, the least cost of material. They create a two-dimensional net of...

Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

The coal is mined. Now what? Scholars design a coal silo that stores mined earth using at least two different three-dimensional shapes. They calculate the volume, determine the amount of mined earth produced in a day, and find the amount...

How many right triangles can you find in a prism, cone, or pyramid? Using right triangles to find lengths in three-dimensional figures is the focus of the lesson. After working with the Pythagorean Theorem to find missing side...

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Before determining the classification of a three-dimensional shape, you need to know about the characteristics of a vertex, edge, and face. Go step-by-step using a prism, and discover what each aspect refers to and how it applies to...

Students investigate the geometric shape of a box. They apply different construction methods and materials to create a three dimensional box. The uses of a box are covered and the measurements taken to consider its uses. Students...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)
