Let's Cooperate Code Cracker - Middle Years

PDF | 32 pages|Grades: 3 - 4

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.

Thanks for the resource.
A quick question about the ‘Ancient Wheel Puzzle’. In the instruction it say ‘Work with your team to figure out the three planet names and which wheel they fit on.’ I can see there is a clue (e) to put Jupiter on the small wheel however the amount of blank tile space don’t really match the amount of letters required for each word. The blank spaces seem haphazard on all the wheels. Is this the way it’s meant to be?

Hi Raina, thank you for contacting us. You are correct in noticing the E in the template being there to set where Jupiter goes. I have noticed that the font is incorrect and that there is an E tile that should not be there, so I will fix that now. The letters are suppose to fill in the blank spaces that do not currently have blank rock tiles on them. The letters are at random on the wheel as it is not required to have them in a straight letter formation because the need is only to line the letters vertically in a way that reveals the number one. The idea is for a group to work together to figure out the planets that best utilise the tiles they have. If you check out the cheat sheet on page 7 of the PDF, it will also help guide you to how the letters are to be placed. If you need any more assistance, please do not hesitate to contact me.

Resource Updates

  • Jupiter tiles of Ancient Code Wheel have all been made singular. Letter tile hint has been removed so all need to be added to the blank spaces without blank tiles.
