In this activity students work in small groups to write the steps to an everyday task or the steps in a "how to" scenario. The steps the groups write serve as an algorithm. The groups will then swap their writing for the teams to now "debug" each other's work to make the steps more precise.

This activity was demonstrated during the Exploring Today's Classroom (ETC) Summit.
