In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this activity, learners use squares to figure out how many border tiles are needed to enclose different areas.

In this activity learners create patterns of hair beads.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

In this activity (on page 134 of the PDF), learners explore reaction time.

In this math puzzle game, learners work together to use algebraic reasoning and fun clues for solving word puzzles.

In this activity, learners develop their understanding of combinations as they create as many different kinds of tostadas as possible.

The popular sudoku puzzles use numbers, but the game could played with any set of 9 different objects!

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this craft activity, learners create a string of cut-out moons and stars.

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 use cubes to calculate how many blocks it would take to build stairways with different heights.

In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.
