Introduction to Computational Thinking Without Technology

Unplugged exercises show that computational thinking is not solely about computers—it's a way of thinking that can be applied to any problem. Whether it's organizing a soccer team, playing a board game, or planning an event, students can practice computational thinking without any digital devices.

Examples and Step-by-Step Instructions

Here are a few examples of unplugged exercises:

Binary Bracelets

In this activity, students create "bracelets" by stringing beads on a string based on a binary code they design. This introduces the idea of encoding information in a binary system, a fundamental concept in computer programming.

Start by explaining the binary number system and how it uses only two symbols, typically 0 and 1, to represent numbers. Then, provide each student with a table representing the English alphabet and show them how to spell their name in binary. They can encode their name by using the table to convert each letter into a binary number and then translate that into a bead pattern for their bracelet. This exercise helps students understand information representation and encoding.

Paper Protocols

In this activity, students simulate the process of writing and following protocols. Ask students to think of a task, such as making a peanut butter and jelly sandwich. They then write out specific instructions for how to complete the task without using ambiguous language. Once the instructions are written, they trade with a partner who must follow the instructions exactly.

This exercise highlights the importance of clarity and precision in instructions, as well as the need to account for all possible scenarios. It also demonstrates how a computer "reads" and executes a program.

Activity 2: Coding Challenges
