My DS is just turning 7 and just gone into Year 2. He has been completely flummoxed by his maths homework over the past couple of nights and got a bit upset. I'd like a sense check as to whether the problems are hard or whether he is not where he should be for his age and I should be concerned. We are not in UK, a lot of the kids in his class seem very bright indeed and so it's difficult for me to judge what would be 'normal' back home.
Maths homework questions are things like, 'what is the difference between 67 and 48?' DS doesn't seem to have a clue and will guess answers like '51' when asked.
Also any tips on strategies I could use to help him would be gratefully appreciated!
