I have an 8yo in year two. I just read him those questions out and he was able to understand them and answer them. But he is advanced for his ago, he is at a year 5 reading level and year 3-4 for maths... He does know his odds and evens and to find/look for patterns in numbers.

Maybe ask the school for some assistance if he is struggling, with my other son in year one, he has a teachers aid spend an hour with him (and some others) to help him with his reading and maths, within a few weeks he is finally getting up to where he should be.

What other type of homework does he get maybe we can compare?
