Problem arose by the school not following up on home work that was asked to be done. Our kid used the system knowing he wouldn't be given any punishment from school to not do the "homework".
We asked why there was no consequences for his failure to hand in his homework, we were told there was nothing the school could do about it. The school told us that there were studies that show no link between primary school homework and preparation for secondary school.
We purchased some Maths Mate style books and started giving him the sheets as homework, that's when we realised how much he has dropped off in his abilities in the past year. He used to be a very bright student for his age, now he has fallen well below the level of grade six work from these books. The books aren't that hard either so...
I believe it may just be the school's and his teachers attitude to teaching the boy, as well as his attitude to not giving a stuff. It appears to be a case of let someone else worry about it at secondary school.
BUT.... surely at grade six level a student should know the afore mentioned stuff as well as multiple digit sums, multiplications, divisions etc.
