Use 20 Questions as a way to introduce binary to help motivate the way binary works in an engaging and interactive activity.

  • Activity:
    • Have students play 20-questions either by playing in class or having students interact with an online system:
    • Explain that we could write down the answers to the questions as Y and N for Yes and No.
      • This could also be written down as 1 and 0 for Yes and No.
    • Discuss the state space of 20 bits—how many items can you represent with 20 carefully chosen questions?
