As you can see, code crackers are perfect to use as a whole-class game where students work in six small groups. 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:

  1. Arrange your students into 6 mixed-ability groups and set up your six stations.
  2. Set the combination locks, with one set to 295 and one to 473.
  3. As a class, read the Season’s Greetings Introductory Poem to the students and ask if they have any questions.
  4. Monitor and support your students as they complete their puzzle. Undo any misconceptions along the way.
  5. Once a group has completed all six puzzles, check the numbers before reading the Holiday Hooray! Final Riddle.
  6. Use the final riddle to work out the digits’ correct order to crack the code (refer to the answers on the Teacher Information Sheet).

Escape Room – Whole-Class Game

To set up an escape-room style game, why not hide a class reward in a lockable box. Need some ideas of what to put into the box?

When it comes to what to put into the lockable box, sweets might be an obvious choice. But, what about awarding your class with an hour of personal choice or a pizza party!
