My DS is 5 and pretty into numbers. He nags me constantly to do sums for him and we do a little bit of adding, subtracting and division every evening using the doodle app on my iPad. I stress that this is completely led by him; I'd rather read a book. He can tell the time so long as it is quarter past, half past or o'clock and has known shapes for what seems like forever. I know none of this is out of the ordinary, but I present it as background. He can do some of these sums in his head, such as dividing 8 sweets between 2 children, for example.
Anyway. I've just opened his report from his first term and his maths target is to practice counting objects, and it is suggested that I get to count 1p and 2p pieces at home to help with this. As an experiment I gave him the connect 4 counters and he counted them up to 40 before he ran out of counters.
His reading and writing targets seem fair enough. I'm really bothered about the maths targets because I feel like they haven't got to know him at all. I told his teacher at the parents evening how into sums he is, and she said that she would look at that with him this term.
How should how tackle this? Should I? He is a very active boy and we were told that he spends a lot of time outdoors at school, building things and often comes home covered in mud. 
. I am pleased about this.
