  • Transum,
  • This starter is one of those you could use today then use it again next week to see any learning which may have taken place. Each time the page is reloaded the questions are regenerated from random numbers so simply remembering answers from the previous time the starter was attempted won't work! Each of the four questions invite a number of different strategies to arrive at the answer and rather than only focussing on the answers it is worthwhile comparing methods used by pupils in your class.

How did you use this starter? Can you suggest how teachers could present or develop this resource? Do you have any comments? It is always useful to receive feedback and helps make this free resource even more useful for Maths teachers anywhere in the world.

Note to teacher: 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.

However it would be better to assign one of the student interactive activities below.
