I am planning to go and see DS (6) headteacher as I think that DS is being taught maths below the level he is at. Am I overreacting?
My DS was a little behind with his maths last year and in the summer I decided to practice with him a bit, and since September we have practiced a bit every day. He has improved little by little, but things seemed to click for him in the last couple of weeks. He adds and subtracts 2 digit numbers and knows his 5 and 2s time tables (and is keen to learn more times tables!
).
DS is in a Y1 group and last week I have seen one of his maths lessons, his book and asked DS what he had done in maths. According to this he orders numbers (words) up to 20, number bonds to 10, adding up with 2 dices, and I saw calculations in his book (3+4, 10+4). He worked well in the lesson, he seemd to like the fact that he can do it easily, but I don't think he is learning anything. Shouldn't his teacher notice if a child can do more?
I spoke to his class teacher (not his maths teacher). She said DS often doesn't pay attention and therefore wouldn't be able to do the work in the Y2 class. Also, she said there are 37 in the Y2 class and she doesn't always have a TA. Did I misunderstand that 37!?
She told me what she is doing with the Y2s and that I could practice that with DS (partitioning, giving change). I explained partitioning to DS this weekend and he seems fine with it, just needs more practice. So, I am teaching maths to my DS now and the school tells me what to teach? 
I am planning to go and see the HT next week as I don't think this is right and that the school should teach him at an appropriate level/differentiate and make provisions for him (I feel I have been told: sorry we can't teach your DS as he often doesn't listen and the Y2 class is full).
Any thoughts?
