I'm in Y4, and my school splits for maths into three groups. I have the 'bottom' one. However I have two new starters who are only in my maths group because they are in my normal class, and three others who's predictions were wrong - all of them would be comfortably in the middle of the middle group.
I'm finding it a lot harder to differentiate when it's 20 children who all really struggle with number (eg. can't reliably add numbers under 10 on their fingers)... and then 5 who are comfortably at ARE. The gap is just so huge! I never usually have ability tables, but I've had to move them onto the same table as sometimes they're doing completely different work, not just harder questions or whatever.
I'd like to have the TA lead them, but I have three over the week and one of them just feeds the answers (I've explained how I want it done so many times!) and doesn't really know much maths. I also have well over half with SEN so I need the TA for supporting them a lot of the time.
Any ideas? I'm worried I'm going to hold them back because of my lack of skills! Can you tell I'm an NQT?
