2D Shape part 1: Names of Polygons Hi folks!

New blog to start my Term 5 shape series. Starting off looking at the naming of polygons. Enjoy!

Was a fun listen

Typical my GCSE interventions are on Mondays! Are there any plans for this to be clipped/recorded?

Compound Measures Part 2: A Minute Interlude See what I did there?

Hi all

Final post of the term, talking about compound measures with trickier units, like minutes.

Enjoy!

Floor tiles arranged like a Pythagoras proof, except vertices of internal square don’t touch the sides of the outer square.

An almost Pythagoras proof found on the floor of the hotel I’m staying in.

Agree on both. If we could convince enough KS2 teachers to get to confs we would be absolutely laughing between us. I feel the disconnect between the two is a huge downside that doesn't get talked about

No blog this week folks, but the units series will wrap up next week to see us into Easter! If you've liked it so far, please share with colleagues, be they secondary maths, science, KS2 or FE!

My year 13s are struggling with reverse chain rule, so wrote these as a bridging task before we look at adjusting to get a reverse chain rule result. #MathsToday #ALevelMaths

A few weeks ago, I asked for different ways a student might notice they've made a mistake.

I'd now love your ideas for techniques that can students use to check their answers.

e.g.
- substitute a solution back in to check it works
- redo a question with a different method

Go through calculator log for typos/retype calculations to ensure typos weren't made! Anyone who has pressed AC gets mocked incessantly.

Would have been far more efficient if the ghost of Christmas yet to come was just an arrow

Compound Measures Part One: Fractional Thinking Quick editing Josh warning: the Substack gods inform me this blog is a tad too long for some email clients (I know, I know, I do like to go on a bit).

Hi everyone!

This week's blog is about compound measures, and how to reframe them so we can eventually bin the triangles!

Feel free to share this with science colleagues too!

Like there are probably 10 definitions that each make sense, like the ones on the other thread, but that's the one I justify with

Continuous data has to start from 0 as you may look for the 0.000001st percentile, so technically (0+n)/2

Marking some exam Qs today
For “Write a power of 5 from this list.” about half of my class (Y11 F) had written 1^5=1, 2^5=32 etc… (none of which were in the list)
And I realised that our language around indices/powers is so unhelpful, and why so many were making mistakes.

Yeah, I was talking to a colleague about my hatred of completing the square and normally doing midpoint of roots. He brought up no-root parabola, and I went digging 😂

Specifically -b/2a to get the x value of the turning point

Been reeling all afternoon in #MathsToday having discovered the vertex formula for quadratics!

Hope this helps? Feel free to reply or DM 😊

LQ is a quarter of the way so (1+n)/4

UQ I would write as (1+n)/4 × 3, I find the traditional way as pictured in yours again has a more alien feel even though it's logical.

Method 2 has a lot more logic. They know when you have two medians, you find midpoint through (a+b)/2.

To find median/quartile position you're doing the same thing, finding midpoint of 1st and nth value, hence (1+n)/2. This also gets rid of people asking 'why n+1 and not just n?

Likely multi-part reply coming:

I would personally use method 2. If you do use method 1, though, I would use markings above or below the numbers, rather than crossing them out. So often they scribble numbers then can't read what was there when they make mistakes or need info for a part b

Understanding Maths Hacks: Squaring numbers close to 100. YouTube video by Peter Mattock

This is the second in a series of videos exploring popular #mathshacks or #mathstricks and the understanding behind why they work. In this hack I explore the trick that allows you to square numbers close to 100 mentally.

Watch the full video here: youtu.be/ZkXl7aaYKaw

Has his become an RTFQLA?

Had 2 tests today and 1 lesson where we did more two step equations. Lessons are planned for tomorrow and Monday tho!
Can't stay after school tomorrow since I'm up on the train to Manchester to go to Teacher Talk Connect.

The front cover of a second chance paper. The paper is based on the first 11 questions of the winter mock exam, and is worth 29 marks. It asks "How do you feel this went in comparison to the original assessment?"

A Level Further Mathematics – Second Chance Papers Have you ever looked back over a mock exam paper and wished you could have a second chance to sit it? Ever been haunted by a silly mistake and thought, “I know I could do that now”? Now is your chance for redemption… 6 “second chance” papers, with shadow questions (same questions, with slightly different numbers), based on the winter and spring mock papers. Available now in the Maths support room (Ash 38 at lunchtime, Tuesday - Friday) Do as many (or as few) as you like, in any order. Once you have marked it, hand it in for your grade/mark to be recorded. Good luck! Followed by a table listing the number of marks on each paper, and the questions they are based on.

In #MathsToday I have used the AQA shadow papers to create some "second chance" papers for my Further #ALevelMaths students, to give them the opportunity to have another go at questions they previously got wrong in the mocks, but feel they could now do. Selling it to them as their redemption arc 😅

Lots of algebra tiles with Year 9 today. Solving 2 step equations.

Unit Conversions Part 2: Ratio Table Method Hi folks!

Hi all

The units series continues, now looking at how to convert with a ratio table...apologies to @fantasticmaths.bsky.social for stealing the gimmick 😂 #MathsToday
