Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Learners explore the technique of embossing through the use of aluminium foil and a three dimensional collage.  In this embossing lesson, students create a sentence with the letters of the word stamp.  Learners discuss a plaque...

High schoolers analyze characteristics and properties of two and three-dimensional shapes in this geometry lesson. They follow detailed directions to use the Cabri Geometry II Application on their TI-89 calculator to construct a...

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Explore the making of a pinch pot using this resource. Learners discuss the properties of clay, including its molecular structure. Then, they make their own clay pot. As they work, they identify the techniques used to make a pinch pot,...

Here is a real-life lesson plan! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Paper mache projects are great for using up paper from the recycle bin. Give your class the chance to create a three-dimensional globe out of paper mache. They'll work to make their globes as accurate as possible, adding proper colors...

Math scholars study conics and how they are used today. For this mathematical lesson, pupils construct and slice cones after viewing a demonstration. 

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students make a tree sculpture. In this trees and the environment lesson, students learn about the parts of a tree, discuss what a tree needs in order to grow, find images of trees in art and nature, use various materials to create a...

Students construct three-dimensional solar system mobiles.

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Students calculate the area of solids. In this geometry lesson, students use formulas to find the surface are and the volume of solids. They investigate 3-dimensional shapes.
