A Few Thoughts on Negative Numbers – mathematicsandcoding
http://blog.ifem.co.uk/a-few-thoughts-on-negative-numbers
Mathematics, mathematics education and computer programming. A Few Thoughts on Negative Numbers. Negative numbers are one of the topics that I find hard to explain. I think one of the reasons is that for us teachers they just make sense – I certainly can’t remember finding them confusing at school myself. 20 times (-3 3) = -20 times 0 = 0 ). But of course we can use the distributive property to also say that. Begin{align} 0 &= -20 times (-3 3) &= (-20 times -3) (-20 times 3) end{align} ). August 8, 2015.

Hierarchy of Numbers – mathematicsandcoding
http://blog.ifem.co.uk/hierarchy-of-numbers-2
Mathematics, mathematics education and computer programming. I had seen pictures like this before as it is the classic way of representing how the different types of number relate, but I wasn’t totally happy with any of the ones online. So I decided to make my own. I used this in a Year 10 Sixth Form taster session. I will post more about this later in the week. I created this image in Geogebra because of how easy it is to draw ellipses and use LaTeX symbols. The file is available here. July 19, 2015.

Mathematics, mathematics education and computer programming. Very Short Introductions – Book Review 1. I love the “Very Short Introductions” series by Oxford University Press as generally they are very well written and accessible to a general audience but not patronising. Here are a few highlights from the book:. I’d encourage anyone to get this book and they are also all 4.99 instead of 7.99 at the moment if you buy them through Blackwells.

Mathematics, mathematics education and computer programming. Thoughts on Edexcel Mechanics 1. Yesterday morning students at my school sat M1, FP2 and the OCR FMSQ papers. This is the first of three posts looking at these papers and I’ll start with the Mechanics paper. Question 1 was a very straight forward conservation of momentum question – as long as you don’t get confused with the direction the particles are moving in there are easy marks to get here. Question 5 was a typical moments question with a b...
