Ever wondered what minuend and subtrahend actually mean?
They both come from Latin — and once you know their roots, they suddenly make perfect sense.
The minuend? The number that must be made smaller.
The subtrahend? The part that must be subtracted.
Little words, big clarity.

Tom Isherwood and Jon Cripwell discuss the benefits of using different colour pens when modelling representations in primary maths lessons. It's a simple tip that can make all the difference to a pupil's conceptual understanding! #twinklmaths

Instead of showing colleagues a scheme activity, Lewis Horsley starts with the curriculum objective.
From there, teachers collaborate on small steps, anchor tasks, hinge questions, scaffolds and challenges.
That’s real collaborative planning.

“The learning in maths doesn’t just happen at the front. It happens when pupils talk, reason and explain their thinking.”
Talk isn’t extra: it’s where mathematical understanding grows.

Lewis Horsley shared a key insight: spacing lessons so pupils forget a little actually helps them learn.
That retrieval process makes maths more durable and meaningful.
Are you planning for spacing and retrieval in your classroom?

“We don’t learn by always being right. We learn when we get it wrong.”
Lewis Horsley reminds us that mistakes in maths aren’t failures: they’re where the real learning begins. What a great message to hear in Y2 - or in any classroom!

The best maths learning doesn’t always happen at the front of the room. It’s in the conversations, the reasoning, the “aha!” moments pupils share with each other. 💡🗣️

As a Y6 teacher, I never received any feedback from my secondary colleagues about how my former pupils were getting on in maths, or if there was anything I could do to support them further. Pete Mattock thinks it's time to change. What do you think? #twinklmaths #EducationMatters #MathsEducation

Could the solution to effective transition from Y6 to Y7 be a closer collaboration between primary and secondary teachers?

Year 7 maths shouldn’t feel like pressing reset.
I spoke with @mrmattock and Becky Dawson about the KS2–KS3 transition, the “Year 7 dip,” and what schools can do differently.

In the 70s and 80s, the BBC had TWO maths sitcoms for schools: Everyday Maths and Maths Counts. I'm launching a campaign to bring back the maths sitcom! Who would you cast in a modern day maths-inspired sitcom?

I love and hate teaching how to categorise polygons 😂 "This is a square. It's also a rectangle, and a quadrilateral, and a rhombus, and..." It's fun to challenge misconceptions and assumptions, but it can also get quite complicated, quite quickly! #TeachingMaths #twinklmaths

Structure or autonomy? Curriculum doesn't have to force teachers to choose. Effective implementation makes all the difference.
