Students examine the different types of polygons and their characteristics. In this polyhedrons lesson plan, 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.
Learners 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.
They're Everywhere! They're Everywhere!
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.
How Many Regular Polyhedrons Are There In This or Any Universe?
Pupils 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.
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.
Examining Geometric Solids
Students make observations and classify geometric solids by characteristics. In this examining geometric solids lesson plan, 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.
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.
Toothpicks, Gumdrops, and Polyhedrons
Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.
Investigating Nets and Polyhedra
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.
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.
Surface Area and Volume
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.
Students analyze convex polyhedra through hands on methods. In this geometrical shapes lesson, students construct paper models of convex polyhedra and identify the different properties including the number of sides, faces and edges.
Lesson One: Perimeter, Area, Volume
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.
Classifying Three-Dimensional Shapes
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).
Geometric Solids and Their Properties
Students explore three dimensional shapes. In this polyhedral lesson plan, 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. For 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.
Give It a Whirl
Students 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.
Crackin' the Musical Code
Students decode musical notation and then synthesize and apply by notating their own musical composition. Students draw various rhythmic examples which are equal in time duration. They notate and count rhythmic patterns. Additional cross curriculum activities are listed.
Shapes with Sticks
Third graders investigate three dimensional shapes. They examine a variety of shapes and the relationship between the number of faces, edges, and vertices. Students determine Euler's formula and they create a variety of three dimensional shapes.
