median don steward mathematics teaching median don steward mathematics teaching 10 16 saturday 10 october 2020 message from don steward s family don steward passed away from covid 19 on 3rd may 2020 throughout his working life he was passionate about improving the teaching of mathematics and has requested that all of his work remains freely available as per his wishes i have uploaded all of his work to this blog in the pages section which contains links to google drive where slides and presentations can be downloaded for free don has also requested that those who use his work make a discretionary donation to charities supporting education in africa this material and other material on don s blog may be reproduced and modified for non commercial purposes under the creative commons

then please email dme lboro ac uk we have set up a justgiving fundraising page to support this wish below https www justgiving com fundraising jessesteward many thanks for all of the kind messages we have received which are of great comfort to myself and the family kind regards jess posted by don steward saturday 18 april 2020 what s gone wrong this problem posed by jack frohlichstein publ dover

questions and so that teachers can adapt questions sorry i m a unicase fan hadieh shafie hadieh shafie hadieh shafie click to link to her website median practice makes perfect blog contents have been moved to this blog apologies if this causes any difficulties e g with links see the pmp tag practice and gcse practice and gcse sheets blog median magic squares blog magic squares resources median choices of ict 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 don steward median pageviews 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 view my complete profile to download a file click on the link download it by
