The latest edition of #MathematicsTeaching from @atmmathematics.bsky.social is giving me wonderful “Smash Hits” vibes with a centre spread poster 🌟
Particular highlight for me this issue is the article from @janehawkins.bsky.social on the importance of purposeful talk in maths 🗣️

More Y9 trig #MathsToday: we ditched the tables in favour of drawing multipliers directly onto the triangles. This lesson went pretty well! Still just using sin and cos, and today I kept everything in one orientation as well.

Three triangles, with working in a ratio table to find a missing length.

The same three triangles and answers with the tables removed, and the title How might we skip the table?

The reference triangle with multipliers drawn on: x sin(a) goes from the hypotenuse of 1 to the opposite of sin(a), and x cos(a) goes from the hypotenuse of 1 to the adjacent of cos(a).

Four questions that have been solved by drawing multipliers onto the triangles

"Based on our evidence and analysis, we believe that the right approach is to maintain a single GCSE in maths... Reintroducing parallel qualifications would very likely widen socio‑ economic gaps, and face the same fate as the failed pilot in England and the abandoned policy in Wales."

"In England, a 2010 pilot that split maths exams into “methods” and “applications” found several problems, including that teaching time became fractured, and that most schools entered students for only one paper, which led to “social sorting” and less value being put on the numeracy paper."

Jay Timotheus @jaytimotheus.bsky.social · May 18

"In our consultations, we heard many suggestions on these issues, including that the above problems could be fixed by splitting GCSE Maths into a more-academic “pure” paper and a more-applied, “numeracy” paper. However, evidence cautions against this."

From the @mathshorizons.bsky.social report May 2025:

"We believe that reasoning and problem solving are not separate strands of maths, to be visited in isolation: they are part of what it means to do maths. The curriculum should reflect this truth at every level."

My final session with @ncetm.bsky.social #Y5to8continuity WG for @nmmathshub.bsky.social. The opportunity to reflect deeply about division of fractions was such a treat - such deep thinking from WGPs. Many thanks @atmmathematics.bsky.social for the inspiring article atm.org.uk/write/MediaU...

Y8 sequences in #MathsToday. This sequence of questions was great!

1) The 1st term in a sequence is 4
and the 8th term is 46
What is the nth term?

2) The 3rd term in a sequence is 23
and the 5th term is 46
What is the nth term?

3) The nth term is 2n + 6
Is 107 a term in the sequence?
Give a reason for your answer.

4) The nth term is 3n - 4.
Is 132 a term in the sequence?
Give a reason for your answer

5) The 1st term in a sequence is 18
and the 9th term is 106
Is 73 a term in the sequence?
Give a reason for your answer

6) The 4th term in a sequence is 31
and the 10th term is 85
Is 98 a term in the sequence?
Give a reason for your answer.

7) The nth term is 11n - 6
What is the position of the term 225 in the sequence?

8)
The nth term is 21n - 41
What is the position of the term 1933 in the sequence?

9) The 10th term of a sequence is 155
The 100th term is 1685
And the 1000th term is 16985
Could the sequence be linear?
Give a reason for your answer.

10)
i) What is the nth term of the sequence of numbers made from the overlap of 3n + 2 and 5n + 4? ii) Investigate for other pairs of sequences.

"Alternatively, with a more connected approach to learning, the more mathematics you learn the easier the subject gets... you have an increasing number of conceptual connections... ideas make more and more sense... and you have less and less to consciously remember." Colin Foster in MT295

Today’s poem celebrates Fibonacci Day. It’s called ‘Word Crunching’.

Word Crunching

I
wrote
a poem
on a page
but then each line grew
to the word sum of the previous two
until I began to worry about all these words coming with such frequency
because as you can see, it can be easy to run out of space when a poem gets all Fibonacci sequency

#MathsEdPoetry day 3 (well almost, I won't have time in the morning!)

The I-we-you structure in lessons can easily become an "I", then, "I-again-but-with-minimal-pupil-interaction", then, "Off-you-go-whether-you-understand-it-or-not" structure instead.

This is a pupil perspective.

A poem about what happens when the I-we-you structure starts to have more focus than the learning.

#MathsEdPoetry day 2.
Both the @atmmathematics.bsky.social principle "the power to learn rests with the learner" and Daniel Willingham's phrase "learning is the residue of thought" point to the idea that learning is done by the learner. It is not something that can be done to them. From MT287.

A poem about the experience of learning.
