I made this:
It’s a simple worksheet where students find the answer to an addition, subtraction, multiplication or division sum and look it up in a grid. This then generates at letter. Once students have found all the answers their letters will spell something.
These kind of worksheets are quite fun. They take a list of questions and turn them into a puzzle, and they’re really easy to make.
You might want to show students the video below before starting the task.
This would set the atmosphere and make the lesson more themed and engaging.
If you use this, let me know how you get on.
