Guess My Number

In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions. Learners play a game similar to 20 questions to guess a number with the strict rule that they can only answer whether the secret number is greater than or equal to a guessed number. This game explores the main principles of Boolean Logic. Activity includes step-by-step instructions with pictures, an explanation of the computer science behind the activity, and optional challenges.
