Update: You can now create custom tests on the full-sized version of the KS2 arithmetic generator. This quick video shows how: mathsbot.com/primary/ks2

In #MathsToday I did this as a starter on estimation. With the aim of getting pupils to consider which counters are the 'significant' ones.

If you want to see my nonsense in person and hate teaching significant figures, this is the session for you!

In #MathsTomorrow I'm going to try and develop a sense of why we round numbers. Any good ones to add to my list?

I used this differently this week. I put a 1000 seconds on the clock and then used it with MWB's with the class. I think it worked really well and was a fun way to introduce prime factorisation. mathsbot.com/puzzles/prim... #MathsToday

In #MathsToday I gave my 7yo the calculation in the box at the top. This was his method.

My favourite thing about the maths teacher community on Bluesky is #MathsToday. If you’ve not joined in before, I can really recommend it. Posting a highlight of your day is very uplifting! I’ve kept forgetting this term, though, so going to attempt a week’s worth in one go…

Demonstrating how we can determine if a number is square by examining its prime factor decomposition, i.e. making two equal columns using Prime Factor Tiles. www.youtube.com/watch?v=pCzW...

No #MathsToday since I don't teach on Thursdays, but I did make this which is quite fun - I added the key stage filters today. mathsbot.com/puzzles/anag...

I keep forgetting to take pictures of cool things we do in #mathstoday to share… so I’ve recreated on notes app 😂 Today Y10 were looking at expanding double and triple brackets and absolutely smashed it. So we spent the last 10 mins working “in reverse” as a taster for their next lesson…

Promised to be better at doing a daily #mathstoday and this is my first post of the term. 🤦🏻‍♀️ Rolled out a Durham Maths Mystery to practice algebra with Y8, they loved it. Lots of resilience. 💪🏻 These resources are 20 years old and I forget they exist, rediscover them & love them all over again.

In #MathsToday I set my Y9 this little "bonus homework" after introducing prime factors. Wonder if they will spot the link?

In #MathsToday, Year 12 and I enjoyed doing some Susan Wall tasks. I particularly enjoyed this one. We matched the graphs up, and then found the coordinates of all the interesting points.

In #MathsToday (well the highlight of this week) A few nice tasks with my Lower Sixth FM task. This one certainly challenged them more than I thought on their rules of indices Pdf available on this page: kshancock.co.uk/aleveltasks....

I wrote this last year but thought it might be helpful to post again: September Routines Some stuff we do at the start of the year in my department www.resourceaholic.com/2024/09/sept...

It's that time of year again - your annual reminder that if you're a Maths teacher and looking for suitable resources for your classes across KS3 to KS5 then do check out www.draustinmaths.com. The site is five years old this week 🎉🎉 and in that time it's amassed over 1000 resources! 1/3

I’m making the change from primary teaching to secondary maths. Any recommendations of maths teachers to follow would be welcome. Thank you. #maths #newdirection

GCSE Mathematics grade boundaries 2017-2025 for Pearson/Edexcel, AQA, OCR and Eduqas

Updated the GCSE grade boundaries page. mathsbot.com/gcse/boundar...

In #MathsToday, @kelly-pd.bsky.social called a cylinder a tube-oid and to be honest it makes perfect sense.

Just gave this a rather significant visual upgrade. It's now quite colourful, matching the textbooks! I've also added in totals, but they tend to be off by a couple of marks from the official ones as they are just the sums of the notional component boundaries. interwovenmaths.com/_GradeBounda...

Collating 2023 1MA1 to 2025 9MA0: email spreadsheet (XLSX, CSV, Numbers) to [email protected] send from school email address include your name and school in email body no student names either 9-1 grade followed by A*-E grade or GCSE/240 followed by A Level/300 any questions?

FYI, I have updated my Edexcel Grade Boundaries page: interwovenmaths.com/_GradeBounda... Some interesting Further Maths component-level boundaries!

Miquel's Pentagram Theorem

It’s high time I engaged properly with the ratio table method and updated my lessons to fall in line. Would be grateful for recommendations/reminders of anyone using them well already/resources I can refer to as a starting point. @mathsjem.bsky.social @studymaths.bsky.social @catrionaagg.bsky.social

Gone for it. @bennewmark.bsky.social

🧵 Next year my team have requested CPD on using tech in lessons. eg Geogebra/ Desmos/ AI. QUESTION 1. Can you help me by pointing me in the direction of good resources that will help me plan sessions for them on these? I’m not a technophobe but it’s not something I do enough either.

So much possible discussion for pupils and teachers.

In #MathsToday we played this. A sneaky way to squeeze in some revision on multiples and lots of fun.

In #MathsToday we made a double-decker-dodecahedron.

In #mathstoday Year 8 we’re considering how to “average out” objects fairly when given out “unfairly” to begin with using @studymaths.bsky.social Averages and Range tiles on Maths Bot. mathsbot.com/manipulative... We added more and more blocks until it became a bit of a pain to move things around…

Comparing exchange rate problems. How often do we highlight the difference between the two? Are you working vertically or horizontally here? What about the question on the right?

@nathanday.bsky.social @arithmaticks.bsky.social @resourceaholic.bsky.social can you help me locate some more amazing resources for ratio tables/ double number lines for KS3? Already been accessing @NCETM stuff! Thanks in advance.

In #MathsToday we looked at the Chicken Nugget Theorem. One of @rjs2212.bsky.social favourites I recall!

It also features in @studymaths.bsky.social's excellent CPD session 'My Top-Five Four-Digit Numbers'. Available at mathsbot.com/cpdMenu (if you're subscribed to the MathsBot Patreon, which you absolutely should be!)

Love it! Maths Venns definitely goes on my list of All-Time Great Task Formats, along with: - Goal-Free Problems (@mrmattock.bsky.social) - Completion Tables (@studymaths.bsky.social) - Change 1 Thing Chains (@learningmaths.bsky.social) - Which One Doesn't Belong - Always/Sometimes/Never - SSDD

Don Steward's Small Data Set Averages Problems donsteward.blogspot.com/2017/08/smal... There's something about how the top rows develop in challenge that is glorious. I've never taught averages without using them. They pair excellently with @studymaths.bsky.social's mathsbot.com/manipulative...

Calling all Maths teachers! What are some of your all-time great tasks for secondary Maths? Ones that could have their place in any curriculum, one that should be studied in PGCE courses, ones that started whole new genres of tasks... ... or just ones you really like. (see some of mine below)

#MathsToday Our final topic of the year in Y12 Further Maths is roots of polynomials. I've made a few new resources for teaching this topic - some fill in the blanks and a crack the code which you can find on my website www.draustinmaths.com/a-level #UKMathsChat #ALevelMaths

A #MathsToday catch-up post: here are some of the things I’ve done this week. Y10 learned about recurring decimals, so I used this Don Steward task (reformatted to remove fractional indices). I didn’t realise how nice the answers would be! donsteward.blogspot.com/2017/02/recu...

New post! 'Conferences and Catching Up'. A write up of the events I've attended in the last couple of weeks and a summary of the current talking points in maths education. www.resourceaholic.com/2025/07/conf... #ukmathschat #mathstoday #meiconf2025

Combining ratios is one of my favourites. First question that's needed a four-row ratio table.

We also did this fantastic task by @drpas1001.bsky.social. It gave so many opportunities to make connections between the different shapes, make predications about whether answers would increase or decrease between questions, etc. www.tes.com/teaching-res... #MathsToday

I'm playing around with a "Models" checkbox which dynamically generates a suitable model for the examples - in this case a ratio table.

This was fun in #MathsToday. Which player would you rather be?

We’ve just organised the cars.
