it may be more appropriate to present ideas and tasks without the ppt offered (where they are)

ppts are provided with, hopefully, some interesting questions and so that teachers can adapt questions

ICT resources that I think are helpful

10 to 16 maths education

ideas are aimed at those who teach mathematics to adolescents; who like tasks with some depth, novelty and a focus on generalising relationships and on transformation
