Every year I think โ€œI should ask Jonny to make me one of theseโ€ and every year I forget.
Can I please have one? And Iโ€™ll come pick it up so we can have a catch up too!

The event runs in a "TeachMeet" style, with speakers sharing for about 10 minutes.
We are particularly keen to hear from Maths teachers ready to share that brilliant:
โœ๏ธTeaching & Learning Strategy
๐Ÿ“ Game-Changing Resource
๐Ÿงฎ Mathematical Idea that has genuinely transformed student understanding.

I would avoid teaching SOH CAH TOA too for the same reasons!
Iโ€™m not against the formulae themselves, just want an understanding of where they come from. If we were all on that wavelength I think it would support us across both subjects.

Yes apologies, I think my comment is where this turned and Iโ€™m similarly not trying to have a go at science teachers, more that this might mean we could share practice much better if this is the emphasis! I feel like many more of the maths community are with me on understanding via proportionality.

Me and @studymaths.bsky.social always do the โ€œfoundation paper challengeโ€ to see how much of the papers you can do with a ratio table every exam series - itโ€™s a LOT!

Question:
What does โ€œvariationโ€ look like in subjects that ARENโ€™T maths?
Are there some subjects where the theory doesnโ€™t really apply?

Yes! The wheel equally shines light on the thing you donโ€™t want, when you THOUGHT you didnโ€™t care ๐Ÿคฃ

Wheel Decide Can't decide? Wheel Decide for you! Set your own custom choices and then spin the wheel to make the random decision (lunch, movie, anything!)

I use something like wheeldecide.com in these moments. Often people know what they really want when it looks like it might be another alternative.
If they really donโ€™t care, it picks for you.

Iโ€™d only really do this with my higher tier groups. But if we drill this enough theyโ€™re able to recreate the table in 30 seconds or so.
For foundation, I show them the table with the simplified versions, then ask them to use it a lot and hope some stick. Sometimes drill the 0.5 and 1sโ€ฆ

Exact trigonometric values in a table for 0, 30, 45, 60 and 90 degrees for sine cosine and tangent.

Exact trigonometric values in a table for 0, 30, 45, 60 and 90 degrees for sine cosine and tangent.

Often I show the triangles to derive and then we fill in a table like the image. Relies on strong surds.
Sin & cos: both have every value over 2.
Sin goes root 0, root 1, root 2, root 3, root 4 (all over 2) then simplify.
Cos in reverse.
Tan = sin/cos mrlyonsmaths.files.wordpress.com/2015/11/trig...

Reached a point where I am starting to have โ€œinside jokesโ€ with some of my Year 11 classes now and itโ€™s making my lessons with them so much more enjoyable - I love the part where you finally feel like youโ€™re getting to know them and feeling like a team ๐Ÿคฉ
