In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

Learners make their own simple slide rules out of paper and learn how they work.

In this math game, learners throw dice and place the numbers in one of four boxes. Learners repeat this three more times and the learner with the largest four digit numbers is the winner.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Coins are everyday objects which tell a lot about the people who use them.

Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

In this math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

Learners use their opponent's clues and a compass rose to find the hidden treasure on a map. Learners use problem solving and coordinate grid skills as they hunt for treasure.

In this math activity, learners play a number game to explore the relationships between numbers, combinations, and the concept of equivalency.

In this activity, learners explore geometry and spatial relationships as they figure out how to arrange tables for a party.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.
