The groups are then presented with a final riddle that helps them rearrange the numerals to crack the code and succeed in their mission.
Meanwhile, students who solve code crackers are having fun while also working to improve these important skills without even realising it:
- critical and creative thinking
- speaking and listening

Code Cracker Activity Ideas
Want to add some more fun to your students’ puzzle-solving? Try these ideas from our teacher team!
Code crackers are perfect to use as a whole class game where students work in six small groups. So ideally, each group will rotate around the six activities and have a go at all of them. Don’t forget to use the Teacher Information Sheet as a step-by-step guide and follow these top tips:
- Arrange your students into 6 mixed ability groups and set up your 6 stations.
- Set the combination locks.
- As a class, read the Season’s Greetings Introductory Riddle to the students and ask if they have any questions.
- Monitor and support your students as they complete their puzzles. Undo any misconceptions along the way.
- Once a group has completed all six puzzles, check the numbers before reading the Holiday Hooray! Final Riddle.
- Use the final riddle to work out the correct number order to crack the code (refer to the answers on the Teacher Information Sheet).
Put the ‘Buzz!’ into your classroom by filling a lockable box with a reward or message that students will want to win by cracking two 3-digit combination locks.
