My son was seven in November and is in class two. I have started using these exercises in addition to his homework as he doesn't get a lot of maths work brought home. I am not a pushy mother but actually enjoy working through this book with my son, they are fun exercises and I only do 1 a night. I have been surprised how much I have learnt too, it's amazing how much you forget, ie. hundreds, tens and unit. I would suggest that you get the revision guide book with it as it helps to explain to the kids and yourself how to understand the phrasing they use. The answers are in the middle of the book, so if in doubt you could always get the answer first and work back from that with them!!! I photocopied the pages for them to work from so that the book doesn't get ruined and can be used again for my youngest!
