Cup Stacking Algorithms – Intro to Coding ActivityThis is a hands-on, unplugged activity I use to introduce my coding unit. Students practice writing clear, step-by-step directions (algorithms) by guiding a partner to build a cup stack design. How it works: Students work in pairs. One student is the "programmer" and completes the worksheet by writing an algorithm using the provided symbols. The other student is the "robot "and works on a separate independent task while waiting. ( I used a fre
