In #MathsToday with Y10 we did this set of questions. I let them choose their preferred method for each question. My model solutions were a ratio table with 100% in the top-left for consistency.

It's been a few weeks since any updates, but here are some new resources from this week's teaching of solving equations: ✨Linear equations with fractional coefficients practice grid ✨Solving quadratics by factorising sort it out www.draustinmaths.com/algebra #MathsToday #UKMathsChat #MathsResources

Every time I visit my mum I’m always reminded of these mathematical placemats.

Just over a week until publication of my new book on the joys and power of curiosity - the perfect gift for someone interested in maths or politics or archaeology or physics or art or poetry - also ideal for anyone not yet interested in those things who should be.

A great total to have if you want to split a bill evenly in a restaurant.

Enjoyed Q25 from the SMC and in particular liked that my own solution isnt one that is demonstrated in their videos #mathschat #maths #alevelmaths

A silly bit of interweaving or a useful task? @nathanday.bsky.social

A brain dump of mathematical misconceptions. Which of these might be avoided through careful teaching?

Left: Requires triangle-interior-angle-sum and straight-angle-sum. 3 steps. Slower? Right: Exterior Angle Theorem (Euclid 1–32). Requires corresponding and alternate angles. 1 step. Faster? Right feels cleaner to me ... I wonder what pupils would think? #UKMathsChat #iTeachMaths

My thoughts and reflections after an excellent #MathsConf39 by @lasalleed.bsky.social www.atulranatutors.co.uk/uncategorize...

A very short primer on mixing degrees of arc with degrees of angle for circle theorems. #UKMathsChat #iTeachMath Historically degrees measured arcs and arcs measured angles. This might feel uncomfortable but remember how we measure an angle today … with a protractor … measuring around an arc. 1/6

NEW: A simple to use interactive table to practise multiplying and dividing with surds. mathsbot.com/tools/surds

Arbitrary and necessary mathematics. One of those most important ideas to consider when planning and delivering maths lessons. Here's my one-slide summary based on Dave Hewitt's article here: www.lboro.ac.uk/media/media/...

I used this task this week to introduce Y10 to simultaneous equations. Drawing attention to important decisions that need to be made. #MathsToday

In #MathsToday (ish - probably last week actually) some activities with Surds. Answers and better quality versions on the website links. kshancock.co.uk/lessonresour... kshancock.co.uk/lessonresour...

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.

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

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...

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.
