Hi I am in a year 1/2 class and I am due to be observed in maths. I can pick any area (but just covered shape/reflection) and obviously want it to be 'hands on, children discovering things for themselves etc. Was wondering if anyone had any ideas? I was going to possibly look at measures - length, but not sure that it might tricky due to differences between year groups - standard/non standard units etc? Any advice would be appreciated thanks!
