  1. Thanks, Robyn.
    I completely agree that it's the understanding that's the important thing, and that different people use/prefer different methods.
    However, I think I might go with an empty number line on Monday and then allow some creativity as the week progresses. I've no TA for a while and I can just imagine that if I give them completely free rein while I'm trying to focus on my target group, there will be a lot of people doing the wrong thing!

    Why not go for the idea of a string of 12cm. 5.2 cm is cut off. How much is left? How can you check your answer?
    Carry on - I have a string 14.6 cm. I cut a piece off. 3.8 cm is left. How much did I cut off?
    That could even be a good practical investigation. How can they check their answer?
    Sometimes the wrong thing is good!! Team work and investigations.
    Of course - this depends on how good they are at decimals!!!
  3. Robyn, I really like that idea: thank you.
