Hands-on Activities
Four unplugged activities that teach computational thinking without a single device.
These activities work in a teacher training session and in a K–12 classroom with minimal adaptation. None require technology, which makes them useful both for building teacher confidence and for campuses where device access is limited.
Decompose a sandwich
The classic decomposition activity — and a fast way to surface hidden assumptions.
Write an algorithm
Participants write instructions for recreating a picture, then watch a partner draw something else entirely.
Human robot challenge
One participant follows instructions with absolute literalism. Everyone learns precision immediately.
Pattern detective
Spotting what repeats in a sequence, predicting what comes next, and building patterns for someone else to solve.
