In this math instructional activity, students use a paper model to build a truncated icosidodecahedron. The instructional activity includes a model that is to be cut out and put together by the student. There is an option to include a...

In this dodecahedron worksheet, students build a model of a dodecahedron. The pattern for this shape is made up of twelve pentagons. This is a worksheet generator, and the teacher can choose if a sample of the completed shape will be...

Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...

Students construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Students use K'NEX materials sets to...

Students listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

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.

In this math worksheet, 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.

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

Students work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

In this geometry worksheet, students fold paper to make a hexaflexagon. They identify the vertex and all six sides after folding and making their shape. This assignment requires 25 triangles and 19 perfect triangles.

Tenth graders investigate the history of geometry and its different shapes. In this geometry instructional activity, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the...

Students explore the properties of rectangular prisms. In this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Students define properties of rectangular prisms. For this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Third graders engage in a lesson that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while following the...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Second graders are introduced to geometry by a teacher made puppet called Geo George.

Pupils review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Students identify the different properties of Euler's Characteristics. In this geometry lesson, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.

Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.

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