GCSE Revision

Tomorrow I am hosting the NCETM’s #mathscpdchat on the topic of GCSE revision. I thought that I would briefly post tonight with a few thoughts and possible ideas for the discussion tomorrow. For me, in an ideal world GCSE revision wouldn’t be necessary as if there is true understanding I don’t believe that you should […]

Twitter Revision Questions

For the last three weeks I have been writing GCSE Foundation, GCSE Higher, AS-Level (Core 1 and Core 2) and A-Level questions to be tweeted out by my school’s mathematics department in an effort to encourage students to do at least some maths revision every day. These are all designed with the current Edexcel specifications […]

Bar charts and the Arithmetic Mean

I’ve just enjoyed reading Anne Watson’s latest blog post “Finding Nemo and Dissection” on the Oxford Education blog and at the end of it was something that I haven’t noticed before. If you represent discrete data as a bar chart, then the arithmetic mean of that data is a number such that if you draw […]

A #mathsjournalclub Announcement

You may have seen that I was a bit stupid and we missed the date of the next #mathsjournalclub because I put the incorrect date in my calendar.  We were due to discuss the article “Reasoning Reasonably in Mathematics” by John Mason et al on the 11th April, which due to my mistake was moved […]

Posing Mathematical Questions

Sometimes I find it interesting to think about what kind of maths I could develop out of a given picture. I’m curious to see the kinds of things other people come up with.  What kind of mathematical questions could you pose using the following four pictures as stimuli:             

Manipulating Constants of Integration

I was recently asked about the integration of , this had come up in the solution of a differential equation. More specifically the fact that there are multiple ways to integrate this:   At first glance these do not appear to be the same, however plotting them suggests that they are part of the same family […]

Edexcel November 2015 GCSE Paper

My Year 11 students have recently sat the Edexcel November 2015 papers as mocks and it was (as ever) interesting to mark these papers and see where they succeeded and where they fell down. For feedback I have written some questions that are similar to a few questions from these papers, such as the one […]

Graphics Changes in MATLAB

I am a bit late to the party here and despite having fairly recently updated to MATLAB R2016a I have only just noticed that graphics have changed in MATLAB (apparently this happened in release R2014b)! Among other things the default colour order when plotting multiple functions has changed as has the colormap used in surf. […]
