Excuse the pun, I'm just quite excited about the Celebration of Maths event tomorrow. Due to the fact that I'm going to the bar modelling session tomorrow (and that I'm a geek who loves doing Maths on a Friday night), I decided to go on a bar modelling hunt using the Foundation paper 1 from the Edexcel GCSE 9-1 Sample Assessment materials.
As a side note, this is the first time I've sat down and properly worked through any of the new SAMs... and man, they are hard! It will be interesting to see what comes out of the Ofqual stuff in the next few months. But regardless, I've gone through and picked out all the questions that (I think) could be done using bar modelling. The last hour has made me re-evaluate my ideas about bar modelling as the absolute best thing that's happening in maths teaching - don't get me wrong, I'm loving it for developing understanding while teaching new concepts, particularly for fractions and ratio, but I'm more convinced that there's still a place for "standard methods" than I was six months ago.
Anyway, here are some mathematical scribblings and ramblings. Due to copyrighting etc, I'm not reproducing any of the original materials on here, so you might want to open a copy of the paper too.
