Does anyone know of any great resources / books / websites which I can use to help me extend the small group of children I have working at level 5a + in my maths group? We have split our three year 5/6 classes and ability grouped them so that I teach the more able children. I still have a small group working at 3a whom I am targeting. They take up most of my time! The KS2 materials I have (including mathematical challenges for the more able) don't provide any real level of challenge if I set the top group to work independently. They benefit from some of the whole class work; explaining their thinking to others and tackling open ended problems from the N-Rich site but I still feel their needs aren't being fully met. One of these children is tackling GCSE questions at home and 'loves algebra' according to his parent. This little boy is only year 5 so I worry what he'll be doing next year in school if he's already bored and is pushing ahead (too fast IMO) at home. His dad is anxious that he is challenged and continues to enjoy maths. I don't really feel either of these things are happening for him at the moment. Your ideas would be appreciated!
