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.
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.
Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.
New Review Build a Geome-Tree
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!
Learners examine the idea of "regularity" as it pertains to geometry. In this geometry instructional activity students complete several assignments that are part of trihedral angles and regular polyhedrons.
In this exploring three-dimensional figures learning exercise, 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 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.
In this geometric solids activity, learners identify given polyhedrons. They determine the number of sides, faces, vertices, and edges. This one-page activity contains approximately 20 problems. Three problems require the student to write a rule and justify answers.
In this geometric solids worksheet, students identify the number of faces, edges and vertices in each polyhedron. This one-page worksheet contains 33 problems.
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.
Students study geometric images and polyhedrons. In this geometry lesson, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed activity, and make media products for a review of the concepts.
Students make observations and classify geometric solids by characteristics. In this examining geometric solids instructional activity, 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.
New Review Nets
Who doesn't like presents? In this three-day introduction to surface area and nets, middle schoolers wrap boxes as a hands-on exploration. They analyze rectangular and triangular prisms and try to form the appropriate nets.
Students calculate the volume of polyhedrons. In this algebra lesson, students are asked to solve a complex problem. They identify the length of the edges and the volume of the shape.
In this end of the year geometry review worksheet, 10th graders solve and complete 140 different multiple choice problems. First, they find the slope-intercept form of a line passing through a point and parallel to a given line. Then, students determine the transformations that best represent an isometry. They also find the measures of various angles if a triangle within a circle.
In this faces, vertices' and edges instructional activity, students experience and study the relationship between the number of faces, vertices' and edges for polyhedrons. Students complete a table associated with polyhedrons that unveils Euler's formula.
