In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

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

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

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 magic trick is based on how computers detect and correct data errors.

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 computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

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 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.

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

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 pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

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

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

In this math activity (Page 17 of the Play Ball! PDF), learners play a game of "baseball" and analyze the results of the game.
