Thought I'd escaped this!

#Mathstoday Last lesson of new content with my year 11 today. Everything after the holidays is going to be revision. I already have my list of topics for the starters and lessons.

#Mathstoday Year 8 had a go at perpendicular bisectors (went well) angle bisectors (less well) and equilateral triangles (well again) with a compass. Had the original lines and angles drawn on a worksheet so one less thing for them to do.

In #MathsToday I tried @theteacherwins.bsky.social's idea of getting the students to take turns answering an #ALevelMaths question, to focus on clearly setting out their steps, so that the other person could pick up from where they got up to. It went really well, and they seemed to enjoy it!

#Mathstoday Year 10 looked at Inverse Proportion and I finally connected the graph for inverse proportion to the reciprocal graph. (How we x2 on one side so we multiply by the reciprocal to get the other side!)

#Mathstoday Year 8 today looked at Scale (And yes this is pretty much to scale!! With the 1cm: 20 miles) Used Pythagoras to find the length of the line then scale factor to get it to be the right length between London and Birmingham for real life.

#Mathstoday Year 11s looked at Venn diagram notation.(Which I still find tricky myself past the basic ones) Used the lovely Dr Austin task to shade in the areas.

Two new transformation worksheets: ✨ Harder reflections practice grid ✨ Negative enlargements practice grid Corrected after my Year 9s found a couple of errors! Find them at www.draustinmaths.com/transformations #UKMathsChat #MathsToday

#Mathstoday Year 9 looked at substitution today, substituting into our algebra tiles to start off with.

#Mathstoday Year 10s did their test today and since it was mostly the same as my last year 10 I could compare the scores. It's nice to know where I thought I had taught better they actually did considerably better on the exam.

Exam tip: always remember to include units/percentage signs etc when answering questions.

In #MathsToday my #ALevelMaths students were telling me about a Pi Day party they had at the weekend, complete with an integration quiz. They were so animated about it... I love teaching students who are unironically excited about being nerds 🥰😁 This lot are going to love university.

#Mathstoday Split up Year 8s lesson. First half looking at pictograms and the second looking at 2 way tables.

Discussing the sequencing of teaching collecting like terms using the power of algebra tiles with @morrismaths359.bsky.social #TTRConnect

On the train to Manchester so decided to read this book finally (Yes but why? teaching for understanding in mathematics) by @edsouthall.bsky.social I'm on Pg 44 but I'm really enjoying it. It's been nice to think about the basics again. (And I think I already have a takeaway)

#Mathstoday Year 11 looked at probability trees today. Started them off with a typical question to find if 2 different balls are picked from a bag (no tree) and alot of them only found one branch.

#Mathstoday 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.

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

#Mathstoday Year 10 had a go at ratio problems today in pairs. Bit more successful than they were yesterday when working by themselves.

#Mathstoday Year 8 looked at Pie charts today. After some practice with just filling in the tables we drew some without needing a protractor. (Then some with a protractor)

Happy International Women's Day to all the wonderful Maths women - cis and trans - here on Bluesky 😀 #MathsToday

#Mathstoday Year 11 looked at the area under a curve today. So lots of trying to spot triangles and trapeziums.

#Mathstoday Year 11s have started doing half papers today. Used a free online pdf editor to cut it in half but it messed up loads of the powers and brackets. It gets sent to repro so can't really say only print page 1,3,5,7,9 etc...

#Mathstoday Year 8 had a great lesson, half of it spent on tally charts and the other half on dual bar charts. I was surprised how many of them remembered how to do tally charts.

#Mathstoday Year 8 did bar charts today and got to use the scaffolded worksheet I made 4 years ago when doing my teacher training. Since then added some questions where they have to spot the mistake.

Started building my Lego at 5pm, next thing you know it's 9:30pm and I haven't eaten dinner. Whoops.

What warning signs could students pick up on that they might have gone wrong in an answer? e.g. - an unexpected negative/decimal answer, - an answer requiring many more/fewer steps than the number of marks would suggest, - an answer that would be weird in context (e.g. a taxi costing £3000) ...

It was super fun to attend last year, enjoyed it so much I said I would talk at this one!

My year 11 Students were given a paper to do over the holidays. I have at least 2 of them that's obviously just cheated on it. Like what's the point, I don't understand what they are gaining from that. I've learnt nothing from their work.

#Mathstodsy Year 9 have started looking at correlation. Lots of describing and plotting graphs.

I found the teacher tapp question pretty hard to answer today as I was a previous trainee. Like this year is better than last year but go further back and 2 of us who trained here now work here.

#Mathstoday Year 11 looked at Density today. It was something most of them got wrong in their mocks but I feel more confident that as long as they remember the formula its no longer an issue.

#Mathstoday Year 8 introducing mode visually (very small groups I like getting the counters out but doesn't work for every group)

#Mathstoday Today Year 8 looked at finding the mean. We started by looking at how to make it fair to share money.

#Mathstoday Year 8s had a lesson on angles in a quadrilateral today First question, what is a quadrilateral, about 1/3 of the class knew. (Both set 3 of 3 groups) We learnt them 3 weeks prior. Thankfully once they knew what it was they could name some.

Not sure what phase of my life I’m in, but here’s that modelling balloon icosidodecahedron nobody asked for! In theory it could be made out of a single modelling balloon, although in reality they don’t make balloons long enough :(

Making use of the split tile buttons to complete the square even if the coefficient of x is odd. youtu.be/eFLhyWYLyZ8 #MiniMathsBots

The @ttradioofficial.bsky.social Connect event on 14th March in Manchester is looking to be absolutely brilliant! In the Maths Strand you'll hear from the wonderful teachers below, along with some brilliant main stage speakers. The event is totally FREE! Tickets at: www.ttradio.org/connect2026

Announcing! Three more fantastic speakers in the Maths strand at TTR Connect! Teachers - Get your tickets for Connect 2026 here, Saturday 14th March in Manchester and it's FREE, link in the comments!

Here's a simple ggb. You can drag vertices around and you can click on the angles themselves to toggle the visibility of the angle sizes. Triangles and quadrilaterals: www.geogebra.org/m/cf34ycez

They updated it! They separated it into measuring angles and angle rules and my link only took me to the measuring angles one. Honestly thought I was going insane with it being different.

#Mathatoday Does anyone know of an interactive angles on a straight line/ around a point/ triangle/ quad tool. The one I've been using changed (and got worse)

#Mathstoday Year 11 had one more lesson on Vectors. (They had been over complicating it) Did end up using the Dr Austin resources. Which I of course had to do first so my brain could get round all of the questions.

I feel like getting a good seating plan is harder than taking any test. I've got these 3 students who can't sit near each other but 2 need to be at the front. These 2 can't be near each other, but they also can't be next to these students. I honestly don't know if it's possible.

#Mathstoday My year 9s have done both these lovely Dr Austin transformation worksheets today. Nice quiet lesson of just concentration.

#Mathstoday Second Year 9 group had a go at Vectors snakes and ladders by @matildewarden.bsky.social and today. Suddenly students were hurrying up the first part of their work so they could play this!

#Mathstoday Year 8 started angles today. One of my favourite ways to introduce the protractor is looking at how to set it up correctly. Students can also easily see what not to do.

#mathstoday (well yesterday) Year 8 have been learning about Pythagoras theorem, they got to use the square root button for the first time but does seem like they need more practice rounding.

🎉 We are excited to announce MC40! Join like-minded people in a celebration of all things maths at City of Derby Academy. 🗓 Date: Saturday 18th April 2026 📍 Location: City of Derby Academy We look forward to seeing you there! 🙌 👉 BOOK HERE: completemaths.com/community/ma... #MathsConf40

#Mathstoday Was just looking at the worksheets on the system and found vectors snakes and ladders. Yes we are now going to be playing that next lesson.
