Thanks. I could use the library (it has a free hotspot) but I think it would be too hard to read on my phone and the experimental browser on my kindle may not be up to it. Might be worth a try though. I would just like to know what a textbook for the NZ curriculum actually includes so i can work out how much of the next couple of year's work he knows. I think he is assessed a year or so ahead but he is not really being given work past what the other kids are getting - but i could be entirely wrong. Our national standard assessment of "above standard" only means 6 months ahead and i have only seen 3 very poor maths samples all year.
