Cuisenaire rods for algebraic expressions
I’ve spent quite a bit of time so far over half term working on the resource areas of my site – one topic I was keen to get a few more resources for was writing algebraic expressions and using correct algebraic notation, as I’m teaching this to Year 7 after half term and my collection was looking …

#teacher5adaysketch – My school shoes
So today’s prompt is “sketch your favourite pair of school shoes”. This was pretty easy, as I only have one pair. I can’t stand wearing heels at school, so flats are my go-to. They are a little boring, but very comfortable – let’s save the giraffe-esque sandals for the weekend, eh? Here’s a picture of the actual …

#teacher5adaysketch – My hobbies
As half term is an opportunity to relax, I thought I’d do something different this week – having seen the #teacher5adaysketch challenge on Twitter, I cracked out my sketchbook and pencils to draw “my hobby”.First though, a few caveats: I don’t have one hobby; I am very very bad at doing lots of different things for …

Love is in the air!
When I was younger, I was ridiculously cynical about Valentine’s Day – I’d wonder why people needed one special day to tell or show their significant other how much they love them, when surely that should be happening all the time. However, as I’m often working late into the evenings (I get in at 4pm …

Circular thinking
It’s another short(ish) post today because I’m trying to make the most of my first weekend of half term and also because I’ve done something weird to one of my fingers and typing/clicking is really painful today (fortunately, this also puts paid to any idea that I’ll be marking books later). Following my post yesterday about integers, …
Zzz…
It’s Friday, half term started three hours ago and I have already spent one hour of that in bed with a banging headache; for those three reasons, tonight’s post is going to be short and sweet.It’s a tiny snippet of German etymological influence on mathematics. The set of integers is denoted with the letter Z (rather than I) …
Romanes eunt domus?
Today was A Level taster day, so I spent the afternoon teaching budding mathematicians/further mathematicians about calculus and complex numbers (respectively), and today’s etymology post is all about A Level vocabulary.Calculus is a good place to start. It’s based on infinitesimals, so the original meaning of the word calculus – a little pebble used for counting – kind …

Origins: m and π
While revising the equation and graph of a straight line today with Year 10, I mentioned the general form y = mx + c, mostly because that’s what appears in many of the revision guides and textbooks. For my part, I’m happy as long as they can distinguish between the gradient and y-intercept and can …
What have the Romans ever done for us?
On my way to work this morning, while stopped at a set of traffic lights, I spotted a man travelling into work by unicycle. He was riding admirably well, but I have to say, it’s not the kind of challenge I’d want to start my day with. Taking my inspiration from the intrepid unicyclist, I’ve …
