Does anyone have a nice activity that is related to rotational and line symmetry but also is basically Christmassy and snowflakey that I can point my yr 7 teachers in the direction of? #maths

I think thats DR Congo qualified then? Costa Rica can't overhaul Jamaica/Curacao in best 2nd place, so if they qualify in 2nd then Jamaica or Curacao would also (not Panama), so DR Congo would have 2nd highest ranking.

covered yr 7 in #mathstoday and got the pyramids out again, this time to teach simplifying expressions, was great fun

Ks5 homework, fortnightly. Assessments for all key stages, every now and then.

I guess the good old "the proof is trivial" is this

Should move to A-level (hides)

sometimes you just need to spend a load of time on stuff and acknowledge it just needs patience esp with LPA

spent last week thrashing out expanding brackets with a grid/area model last week with grade 1-3 yr 10s, felt like I was going nowhere fast and encountering lots of difficulties.

This morning did reverse process to factorise with same model. Insane success rate.

"We may not all be teachers of mathematics, but we are ALL teachers of math attitudes." @themathguru.bsky.social is delivering our closing keynote for today. 😍 #ATMNE25

Met with Further Education Mastery Specialists across our region today to think about how we can bridge the gaps for students between secondary and FE, and for teachers in our shared understanding of each others' sectors #mathstoday

Later in lesson I gave them f(x)=(x²-1)/(x²+1), {x:x>0} to find the inverse function of

Nice little activity with further today, give them a function, eg f(x)=x²+1, {x:x<3}, and they have to say whether it is many to one or one to one, and if it is many to one a reason why (eg in this case f(-2)=f(2)), & if it is one to one to give the inverse function #alevelmaths #mathstoday

do you think that's your own preferences or do you think there's a hierarchy of loveliness?

When i was a student teacher (08/09) my placement school had such big portions for lunch it would be my main meal of the day during the week.

Here's mine. Was a genuine delight to see angle addition formulae in the wild 🤣

Circle(s) is the key, I think!
It seems like we don't even need those two angles (a, b) to be equal.
In this diagram, the shaded triangles are congruent (SAS) and so both bases are 5root2.
[Seems too simple - am I missing something??]

This is really nice!

pentagon has 5 sides...

Learning how to research is important
So much of life depends on what questions you ask and how you frame them.

As HoD, I've been asking "how do I get more 4+ in yr 11?" But now I'm asking "How do I use yr 9 to get all students 4+ ready?" Changes perspective and data and actions.

The diagram shows two squares, OPQR and OSTU. Point S lies on QV. Triangle UQV is isosceles with a right angle at V. Square OPQR has area 25. What is the area of square OSTU? A 36 B 45 C 50 D 54 E 60

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

Then it started pumping all sorts of bile into the timeline and the Southport riots and I was done

When he took over my engagements just sunk... went from about 200 likes every time i put a resource out to barely in the teens. It's completely useless.

How do you even begin to achieve this?

Cat is home 🏡 thanks for the positive messages! ❤️

anyone got any positive missing cat stories? 😒

what's the longest yours has gone missing for? We are just over 48 hours 😪

“What is three-quarters, one-quarter of?”

My thinking to get to an answer was way more convoluted than it needed to be!

The follow up in my head was what is one quarter, three quarters of, and I actually love this answer and the generalisation that ensues

This is awesome

differentiating x^2, x^3, and x^4 by factorising (x+h)^n - x^n using the factorisation of a^n - b^n and letting h → 0 without expanding the second factor.

Can't say I'd thought to do this before. #mathstoday
