Shapes
Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

Guess My Shape
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.

Designing 3d Products: Candy Cartons
Wouldn't it be great to work in a candy factory? Learners get their chance as they first design a carton for a candy that meets certain requirements. They then examine and analyze nets and explanations in sample student responses.

Living in a Geometrical World
Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Poly-Mania
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:...

Designing a 3d Product in 2d: a Sports Bag
Sew up pupil interest with an engaging, hands-on lesson. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

3D Computer Imaging Class: Cross-Section Lesson
Students use 3-dimensional materials to create a simple 3-D object. They think about different ways the object could be sliced. Students choose one way to slice the object, and draw the sliced shape on paper or computer. Using a 3-D...

Polydron Fun
Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Science Buddies: Shape Changing With the Cyber Squad
In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...
