Explore Straight Lines You could use the Desmos Graphing Calculator to explore straight lines. Suppose you want to have a look at the graph of y = 2x+1. All you need do is click and type your function. Note that you can easily change the colour of the graph (particularly useful if you have more than one graph on the screen). Simply click edit then choose your colour. If you select Options you can easily change the axes. It is possible to print a graph if you are signed in to Desmos (creating an account is free or you can sign in with Google, Facebook or Twitter) – just select the print icon You can use sliders in the Desmos calculator to explore families of graphs. Now click on the image below and try changing the values of m and c and see the changes to the graph. With m=2 and c=1 we can see the graph of y = 2x+1 which has a gradient of 2 (note that for every one unit across you go two units up) and an intercept (where the line crosses the y axis) of 1.

cavmaths After World Maths Day…. UpdateOn the World Education Games Website we can see the following message: The World Education Games will be taking a break in 2014 from official competition and will return in 2015. From an announcement in December 2013 we learn that the World Education Games will be a biannual event, taking place in March 2015, 2017 and 2019. The Exact dates for 2015 will be announced in March 2014. You can read the announcement on the World Education Games blog. So the event is over for 2013, so many questions answered by so many students and lots of fun, the numbers have been crunched here. Perhaps time to remind everyone who enjoys these mental arithmetic games that there are plenty available they can still enjoy all year round. Sum Sense from Oswego City School District Sum Sense from Oswego City School District. for example is a little different – arrange the given numbers to give a correct statement.

Musings of a mathematical magpie If you’ve had a look through this blog before, you might have read the “about me” section at the side where I explain that I did a history degree before going on to become a maths teacher. This information mildly interests some people, worries others, and sends a select bunch into a heightened state of moral outrage. This last group – the righteously indignant - are of course the most entertaining, and I’ve learned to develop a thick skin when they air their short-sighted opinions. Upon hearing the news that I had a history degree, one man abruptly stopped the perfectly pleasant conversation we were having and started spluttering “I wouldn’t let you anywhere near children” before walking off. Another person reacted by saying that I could never be taken seriously as a professional and surely I should be teaching primary school children. So I’m taking the opportunity to answer these two questions about myself. For me, there have certainly been benefits to this approach.

Mathematics Posters A consistently popular post on this blog is the one on Mathematics posters. An excellent new addition to the list of sources of free posters is Jenny Eather’s Maths Charts which includes over 200 posters on a wide variety of topics. (Jenny Eather’s dictionary is also excellent). For a list of sites including free posters use this Diigo list or Evernote shared notebook. To highlight a small number of the sites on the list: Nrich have turned many of their excellent problems into attractive posters. The Classic Mistake site has a wonderful collection of those classic mistakes that teachers regularly see. The Mathematical Moments site features many downloadable pdfs, posters which show the role that Mathematics plays in Science, Technology and Human Culture. On TES Resources Owen has created an excellent set of A4 posters inspired by Ian Stewart’s ‘17 Equations that Changed the World‘. The excellent Maths Careers site includes many posters to download, ‘When Will I Ever Need Maths? Like this:
