Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson plan, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...

In this math worksheet, middle schoolers develop cognitive and geometric abilities. They construct a paper model of a octahedron composed of eight triangular faces, six vertices and 12 edges.

In this math worksheet, students read about the truncated tetrahedron and then create a paper model. It should look like a solid comprised of 4 regular hexagonal faces, 4 regular triangular. faces, 12 vertices and 18 edges.

In this math worksheet, students create a paper model of a snub cube. It is an Archimedean solid comprised of 6 square faces, 32 equilateral triangle faces, 24 vertices and 60 edges.

In this math worksheet, students construct a paper model of a tetrahedron. They create it to have four triangle faces, four vertices and six edges.

Learners explore the concept of euler paths and circuits. In this euler paths and circuits lesson, students discuss the bridges of Königsberg problem. Learners discuss how to determine if an euler circuit exists. Students discuss the...

Students create lines and shapes with a compass and a straight edge. In this geometry lesson, students investigate square roots, irrational numbers and spirals. They explore nature to see the shapes representing mathematics and geometric...

Creating with an app is nice. But, creating with an app and being able to print and use your creation is great! This tool provides the opportunity to hone the skills related to spacial awareness, three-dimensional thinking, creativity,...

Reinforce basic geometry skills in an elementary math lesson. A simple activity prompts learners to identify and label 3-D shapes.

Students explore geometry by defining a list of vocabulary terms. In this shape characteristics lesson, students identify a number of different shapes and discuss the amount of edges, vertices, and faces using the Euler formula. Students...

Pupils work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

Students go through various construction techniques needed to bisect angles, lines and arcs, construct a perpendicular from a vertex to a line, construct the center of a circle, transfer an angle, and various other constructions normally...

In this math learning exercise, students examine 4 pictures of 3D objects and write the name of each. Students then study 3 pictures and figure the number of faces, edges and vertices on each.

In this math instructional activity, students study the properties of plane shapes and solid figures. Students fill out a chart after they have calculated the number of flat surfaces, edges and vertices.

In this shapes worksheet, students identify shapes and the number of  edges and vertices of each. A reference web site is given for additional activities.

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...

Did you know that a soccer ball is very similar to a truncated icosahedron? Both have 32 faces, but while a truncated icosahedron is made up solely of flat hexagons, a traditional soccer ball has 12 pentagons and 20 hexagons, each curved...

Learners reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Watch as matrices break networks down into rows and columns! Individuals learn how a network can be represented as a matrix. They also identify the notation of matrices.

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

How many sides does that polygon have? Building directly from lesson plan number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...
