In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.

Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.

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.

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 activity, learners discover that training a robot can be hard work! Learners investigate how robots complete a task by following a list of sequential instructions.

Here's a very simple activity if you have paper and scissors: make one cut, unfold, and you have a beautiful star! A great way to learn about polygons and origami mathematics.

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.
