29 pages (PDF)|Suitable for Grades: 4 - 6

A whole class game including a collection of 6 activities which students need to solve to reveal numbers to combine for a lock combination.

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.

This teaching resource has a PDF that includes teacher instructions, activity answers, activity templates, task cards. Also available in lower and middle year levels.

  • Kim Jorgensen

    Thanks for a great resource. There’s just a small typo to fix in the HIDDEN OBJECT Riddle, 10th line -places instead of placed: Your next digit will be places on its underside.

    I will be using this for sure. Just a note, you state that UV pens are available in the stationary section. I’m sure you don’t mean a section where you stand still.

    Hi, Kids loved it when I did it today
    – the illustrations lined up with a c instead of a t though making the number t)
    – the questions on the wheel also aren’t in the right order

      Hi Rachelle, thank you for reaching out to us. Thank you so much for your lovely feedback. I am glad you class enjoyed the games. The code wheel was designed to be in a random order, so the players need to work together to figure out where they go. The order of the questions do not correlate to the positioning on the wheel. In regards to the illustration task, we have done checks on our end and the letters match up, however, sometimes changes can be due to a printing setting, so will provide a link that may help size it correctly. If you need more assistance, please do not hesitate to contact us.
