Note to teacher: Each time this page is refreshed the calculations are randomly generated but the message to decode remains the same. There are however ten different messages which can be found by clicking one of the buttons below. The calculations include larger numbers the higher the level.
Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated. Click the button above to regenerate another version of this starter from random numbers.

Here is the URL which will take them to a related student activity.
