The Book People have got a set of 31 of these for £15 at the moment, DS is really enjoying his Chip and Biff books at school, (he's Yr 1 and comfortable at Level 4 at the moment). I get the impression Level 5 is where it gets quite a bit harder.
Has anyone tried these and are they useful? It says there are 5 levels, but at school the ORT has a lot more levels than that, I wondered how the two match up? Don't want to find that they are all too easy.
Thank you.
