I'm a trainee teacher on my final teaching placement and tomorrow I'm teaching them what each digit represents in decimals, rounding and ordering them (1dp, 2dp etc) and marking decimals on a number line. Does anyone know where I can get a number line to use on the whiteboard and how to make this lesson exciting? I have prepared worksheets but they seem really boring and I don't think it's going to stretch the higher group. I taught the class for a week before easter and the higher group found the work easy and got through it really quickly. I'd followed the advice from my teacher but they did much better than I had expected (it was coordinates work).
