From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

Expose youngsters to 3-D objects in a hands-on learning activity involving marshmallows and toothpicks. Engage your young mathematicians by introducing them to 3-D shapes by means of a story book. Explore 3-D shapes by manipulating...

Discover different dimensions with paper folding. Pupils first read about zero, one, two, and three dimensions, and then learn about the fourth dimension, time. They then use origami to create models of shapes in three dimensions and use...

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!

How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...

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...

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...

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

Students view a film about Hans Hofman and consider his use of color and layering. They experiment with the concept of 'push and pull' by using warm and cool color schemes in a tracing of leaves and shapes. Students view their work using...

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, students need to determine...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

If you're finishing up a unit on cells, here's a great project to get kids collaborating and recalling what they've learned in a fun and tangible way. Small groups create plant or animal cells out of materials they have at home. They use...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

After getting to know the inventor, Leonardo da Vinci and his many inventions, scholars think up their own invention. Following a written description and a hand-drawn picture, learners use a method of mirror writing and antiquing to give...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

A succinct overview of colors and shapes with links to two shape games. In Shape Name Memory Challenge you match the shape with its name. In Three-Dimensional Shape Quiz, you must answer the quiz question by clicking on the correct color...

This lesson describes three dimensional shapes and provides two interactive practice activities.

You don't have to be a trained artist to create beautiful two and three-dimensional art projects with your preschoolers. Many simple activities, such as painting and coloring, can be modified to include sensory elements to increase...

Exploring Three Dimensional Cubes This App contains two familiar tools, Logo Light and Isometric Dots. Draw two-dimensional shapes using the programming commands in Logo Light. Draw representations of three-dimensional cubes using...

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

Did you know that two-dimensional shapes are also called polygons? This lesson describes the various 2-D shapes and includes two interactive games to reinforce skills.
