Can anyone tell me if it is normal for maths ability to waver around a lot at the age of 7-8? My DS was doing well in maths in yr 2, but over the last year has slid down from top 1/3 of class to middle 1/3 and now to bottom 1/2 of class...school seem unconcerned but it seems alarming to him (different coloured groups they use) and in turn to me. As a hitherto unpushy parent the yr 2 maths was not the result of my doing anything at home to help. He's good at chess and seems to get things fine when i explain them to him. has anyone else experienced similar??
thanks
