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 puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

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.

This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

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

In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

In this design challenge, learners will use computational thinking to design their own board game.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

When a lot of people share one network (such as cars using roads, or messages getting through the Internet), there is the possibility that competing processes will create a “deadlock," or an interrupt

In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.

In this number puzzle/trick, learner #1 thinks of a number between 1 and 63. Learner #2 shows learner #1 six cards and asks them whether the cards contain their number.

In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.

This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.
