Posted last week regarding maths homework for y7 dd that was too complicated and to get the solution she would have needed knowledge of conditional probabilities whereas in fact she has only the knowledge from primary as secondary haven't covered probabilities at all yet.
Dd has autism and a statement and whilst she is top group she is in no way talented at maths and doesn't even particularly enjoy it.
Had some good advice on how to explain the workings to dd but also advice to raise this with the teacher. In fairness I have written twice in dd's communication book that the problems set are beyond dd's understanding and knowledge but still she gets more.
HofY phoned regarding incidents where dd has been bullied and so I asked if he would raise homework concerns with teacher. HofY didn't have a clue what I was talking about because he's a PE teacher but reassured me that the homework is appropriate to the ability of the class. I said in that case dd must be in the wrong class or the teacher needs to be aware that dd needs the homework differentiated as it is so far beyond her ability and understanding.
Dd handed in the homework which was done with far more support than I think I should be giving and today discovered only she and a friend out of the class of 30 got it right. Dd quite rightly said my Mum did it because I didn't know what to do and her friend said her mum and dad did it together.
Teacher then said tell your Mums well done, I'm impressed 
Why on earth would he set homework knowing that a parent would end up completing it? What does it matter if I can or I can't do the homework? Surely it should be for dd's benefit not mine?
It's 30 odd years since I did maths o level and a level, I'm more than a bit rusty and don't even know if the methods I use are what dd will be taught. If I thought it was an oversight I was wrong as this week's homework is again wholly inappropriate 
I would refuse to do it but dd is so scared of getting in trouble that it's not really an option, I've written twice and raised with HofY now so not sure what else to try.
