The largest was obviously D said Liz. She knew that F was the least straight away. Liz likes these because they are fun. Leechy was confused!

We found out that the difference between any two letters is the same, whatever the start number, e.g.
Using 10 as your start number A=30 and B=40
Using 1 as your start number A=12 and B=22
The difference between A and B is always 10. It works with any pair.
If you divied the number first it will have the least affect at the end number.
Year 9 Shapwick School, 9G
We found that the difference between A and B was 10 for any starting number. Our largest total was D. We enjoyed this starter.

I am not a teacher, but I would think that this would emphasize to students that the order of different mathematical operations make a significant difference as to the final outcome.

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.

Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments:

Transum.org/go/?Start=January24

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