median resources

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

sorry, I'm a unicase fan...

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

about me

don steward: my interest is in effective tasks for teaching mathematics to 10 to 18 year students ~ I have collected and trialled many people's ideas for tasks for many years and have played at making these work ~ my thanks to these people
