Hooray for chocolate chip cookies! Ask your mathematicians to triple a chocolate chip cookie recipe and then reduce the recipe by one-fourth. Your class may need two days to complete, tripling the recipe the first day and reducing the...

How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Students connect literature (story Jelly Beans for Sale by Bruce McMillan) to math concepts. In these estimating and money lessons, students work with jelly beans, unifix cubes, pennies, nickels, dimes, and quarters, to estimate and make...

Few things can motivate children to learn like the promise of a sweet and tasty treat. Given a bag of M&M®s, Skittles®, or other colorful candy, students first predict the contents of the bag before counting the pieces,...

Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

How much rain can that cloud make? Through a simulation, the class estimates the amount of candy rain contained in different cup clouds. After probing the clouds using different methods, class members adjust their estimates. Participants...

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Did you know that leaky faucets waste $10 million worth of water? Conservationists perform an experiment and draw best-fit lines to explore how the US Geological Society determined this value.

Measurement Teaching Theme provides an excellent collection of free sample worksheets, teacher resources, lesson plans and interactive media for the elementary grades.

This activity introduces students to the importance of benchmarks when estimating measurements.

This activity will introduce and/or reinforce estimating the measurements of angles.

Students will estimate various dimensions of objects located in a classroom. After estimations are completed, students will measure objects using appropriate measuring techniques for preciseness.

In this activity, students estimate statistical measures and find confidence intervals.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This part...
