I've enjoyed starting to build mrhardymaths.co.uk - providing quick Do Nows, and practice/revision sheets.

If you've taken a look - I'd love to know what you think.

Student loan interest is back in the news again, and rightly so.

About 18 months ago, I wrote a blog post about the impact student loans have on take home wages and how it's getting worse.

Back then, I said my student loan debt was Β£70,000.

Today:

In #MathsToday I ran a lunchtime session with some year 12 students where we looked at this activity. Trying to get them into the mindset of "just trying things and talking about what you're doing", with the eventual idea of leading to Oxbridge-interview-style questions

Got these questions ON REPEAT with my year 13s at the moment. Almost finished integration and these crop up basically every lesson in #Alevelmaths #MathsToday

I love writing questions based on fun maths challenge qus and found these I wrote a while ago that I really like

School Internet wasn't working very well so not as much done as would have been liked (at least next week is off for us)

Some of my year 10s got to challenge themselves with these lovely Corbett questions.

Love these questions the year 10s did for factorising quadratics. Gave students a lot of the scaffolding they needed allowing them to move onto similar ones without the scaffolding after.

A silly bit of interweaving or a useful task?

Lovely #oracy work on indices in #MathsToday. We haven't covered negative indices yet but this got them pondering negative indices and considering non integer values for a and b as well as 0 and 1. Looking forward to delving deeper next lesson.

Solution to a question on finding the equation of the perpendicular bisector of points (4,-3) and (-2,7). Use of colour to highlight how parts connect to the question words.

Solution to a question on finding the equation of the perpendicular bisector of points (4,-3) and (-2,7). Use of colour to highlight how parts connect to the question words.

I really do think that colour is helpful to identify steps in multi stage problems. But there is also scope to use it to link parts of a solution to the words in the question.

@mathforge.org has done what I’ve never been organised enough to do myself, and catalogued every #geometrypuzzle I’ve ever posted on social media. It looks amazing!

Helping pupils to transfer their understanding into novel context is a notoriously difficult thing to do, but there are some strategies that you can try out.

Take a look at our sketchnote to get started.

Mock Time for year 11s so also a fun time to make resources based on topics they struggled with!

Wrote a post about it here: chelekmaths.com/2025/11/19/e...

I was rubbing this off the board as Y7 came in for the next lesson, and two of them asked why I was teaching discrimination in maths. (I told them they’d have to do A Level to find out!)

With Year 12 today we were looking at remainder theorem and we did the very lovely true or false task from Integral maths. See also here my mini-whiteboard check before letting them get on which was nice as it forced them to think about the positions of the numbers.

#MathsToday "Slanty" shapes were turned into right shapes by imagining them as stacks of paper which needed a push. This helped us identify needed lengths and ignore distractions.

The aim was long-term learning, not short-term performance obtained by using formulae. Time will tell.

Today’s Y13 starter - I really like how c & d can be solved either by changing the inequality and using the original distribution, or by transforming the distribution and using the original values. #MathsToday #ALevelMaths
