Measurement matters! The mathematical theme for the NRICH site (<http://www.nrich.maths.org/public/index.php>) this month is "measurement and trigonometry". The problems aim to help you think about the relevance, variety and scope of measurement. You think you know what a square is? How about playing Square It (<http://www.nrich.maths.org/public/viewer.php?obj_id=2526&part=index&refpa ge=monthindex.php>)? Can you find a strategy? For some "real world problems" how about trying Sizewise (<http://www.nrich.maths.org/public/viewer.php?obj_id=2372&part=index&refpa ge=monthindex.php>), Chocoholics (<http://www.nrich.maths.org/public/viewer.php?obj_id=2416&part=index&refpa ge=monthindex.php>)and An Unhappy End (<http://www.nrich.maths.org/public/viewer.php?obj_id=2384&part=index&refpa ge=monthindex.php>)? The History of Measurement article (<http://www.nrich.maths.org/public/viewer.php?obj_id=2434&part=index&refpa ge=monthindex.php>) gives insight into the ways that different civilisations have developed measuring systems in the past. Don't forget to use the Maths Finder to find some of our past measurement problems, games and articles.
