I teach maths in a Scottish state-sector secondary school.
Stuck in the middle with Hughes.

Some skillfully-presented and adorned work in #MathsToday.

Pity the content is not yet to the same standard.
Back to the drawing board, I suppose.

Got a real buzz in #MathsToday checking these homework submissions. I love it when pupils have the ability to navigate a question and express their solution strategy in their own unique way. They seem to be developing the relational understanding I would want them to have.

Greenhead Moss, Wishaw, North Lanarkshire is home to a raised peat bog. These stairs aid access to the surface of the bog. The numbers on the risers, not quite an arithmetic sequence, indicate the age of the peat at the corresponding depth.

I only discovered it a couple of months ago: a colleague lent it to me for summer reading. I thoroughly enjoyed it.

Regarding amicable numbers, here’s an extract from Wikipedia. Perhaps your students would be interested to hear about Niccolo Paganini - see highlighted passage.

Simultaneous Linear Equations with my S4 class in #MathsToday.

These tasks seemed effective in delivering my aim to help consolidate learning to date and with general sense-making.

Just realised my wording could be better in task 2.

I’m interested to know if those who got Q2 correct got all three correct and if those who got Q3 correct also got Q1 correct.
I would like to think so, but maybe not.
(I’ve tried to represent this pictorially)

Teachers in Glasgow (and elsewhere in Scotland) are back in schools tomorrow, pupils returning on Thursday.
I’ve been assembling a garden bed this afternoon. What maths can I do with my pupils using this as a prompt?

The reviewer, Stitcher 78, appears to have both a wife and a husband. As Groucho Marx once said …

Episode one features new evidence suggesting Homo sapiens existed 300 000 years ago, one third more than the previously accepted estimate of 200 000 years. Cutting edge, indeed.

More last day mini-whiteboard maths.
What is each catchphrase?

Last day of the school year here in Glasgow. Having some fun on mini-whiteboards with senior pupils.

This was reasonably effective in #MathsToday with my new Advanced Higher class. They encountered the product rule for the first time last lesson.
