Learners make three dimensional shapes with nets. For this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

The objectives in the resource allow students to explore the characteristics of simple solid shapes. Youngsters learn to recognize the face shapes, corners, and edges that make up 3-D figures by filling in a chart. Lastly,...

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Students calculate the volume of different polygons. In this geometry lesson, students identify the relationship between base and height. They calculate the area of each prism and cylinder.

In this geometry worksheet, 10th graders respond to journal prompts related to prisms and classifying solid shapes.  The two page worksheet contains nine questions.  Answers are included. 

Students calculate the surface area of different prisms. In this geometry lesson, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

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...

Learners create nets of cylinders. In this geometry lesson plan, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.

Fifth graders use formulas for calculating areas of squares and rectangles to find area of complex figure, compare their own ideas with their classmates' ideas, and recognize that there are multiple methods for finding area of complex...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
