Start your classrooms school year with a bang and help students introduce themselves to each other with the Let’s Cooperate Code Cracker! Students need to work together on 6 tasks to reveal 6 numbers to crack a lock combination. The groups are then presented a final riddle to help them arrange their code in the right order to help them succeed in their mission. Get a 6 digit lock or 2X 3 digit locks and a lockable box to hide a reward or message for students to compete for.

Run this activity as a timed rotation system for six groups on six activities or create it as a race to the finish. As previously seen with Teach Starters, Marvin Measurement’s Treasure Box and Christmas Code Cracker, students love working together on the variety of small group tasks, where students need to communicate and cooperate together to help each other succeed.
