Students examine the different types of polygons and their characteristics. In this polyhedrons lesson, students discuss the derivations of specific models of polyhedrons. Students work in pairs to make a copy of a polygon model, then discuss the strategies they used to solve various problems with polyhedrons.
Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve information on polyhedras on the Internet.
Students examine the idea of "regularity" as it pertains to geometry.  In this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.
Students gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.
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: This resource references a 14-minute video which can be found on the web with a search.
Students make observations and classify geometric solids by characteristics. In this examining geometric solids lesson, students classify three-dimensional geometric solids. Students examine why classification of geometric solids is important and how this knowledge helps us. Students construct three-dimensional figures using geofix shapes and polyhedrons and test the strength of different solids.
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They define the term polyhedron as a closed three-dimensional surface formed by polygons.
Sixth graders explore three-dimensional objects. In groups, they create and decorate their own polyhedron design. After identifying the faces, vertices, and edges of the polyhedron, 6th graders determine a relationship between the faces, vertices and edges.
Students discover the characteristics of polyhedra. Through hands-on activities and interactive videos, students investigate and retrieve information on polyhedra and crystal structures. Students study angles and symmetry. They participate in an Internet Scavenger Hunt.
Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.
An outstanding lesson on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed video, and engage in games and in-class activities that should strengthen their understanding of the world of geometry.
Pupils calculate the surface are and volume. In this geometry lesson, learners create nets of their different polygons. They find the area of nets and prisms as they define the parts of the polygons.
In this exploring three-dimensional figures worksheet, 10th graders solve 111 various types of problems that include three-dimensional figures. They create a model of each figure and draw the back view for each one. Then, students identify the number and type of polygons that are faces of each polyhedron. They also find the lateral area and surface area of each right prism or right cylinder.
Students analyze convex polyhedra through hands on methods. In this geometrical shapes lesson plan, students construct paper models of convex polyhedra and identify the different properties including the number of sides, faces and edges.
In this geometry learning exercise, 10th graders solve polyhedras by name, net and solid by finding the surface area and volume of each shape. This learning exercise has 10 questions that are problem solving type questions.
Students explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups, students estimate the number of cubes that will fit in containers. Students build a polyhedron and calculate the perimeter of the base and the volume of the polygon.
Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes worksheets, notes, a chart to record the properties of various solids, and a brief quiz assessment (with no answer key). 
Students explore three dimensional shapes. In this polyhedral lesson, students understand the composition of three dimensional figures through the use of the "Geometric Solids Tool." Students compare and contrast different shapes.
Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials from previously learned materials.
Young scholars examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.
