There is some. For example, in our context we have a large proportion of EAL pupils who are good at algebra. These pupils can perform better on higher tier paper.

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?

Sorry, I did a maths joke. 60! Is a really big number.

Jonathan Hall @studymaths.bsky.social · 4d

60+60! is a ridiculous claim. I can just about do 4!

Ha, I think that makes us even for the favour I asked earlier this week!

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.

Here's a quick tutorial I just made for it.

A very windy 6k for me. Lots of branches down to hurdle.

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/...

Mathematical conventions must be explicitly taught, but mathematical ideas can be discovered or deduced.
Dave Hewitt refers to these as arbitrary and necessary.

A couple of tasks to bring about awareness of the properties of odd and even numbers.

I used this task this week to introduce Y10 to simultaneous equations.

Drawing attention to important decisions that need to be made.

#MathsToday

"What's the same and what's different?"
4 pairs of simultaneous equations with very similar coefficients.

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

Maths worksheet titled 'Multiplying surds'. Students are instructed to pair surds from a 3x4 grid (including values like √7, 2√3, √48, etc.) to match answers in boxes below (e.g., 14, 6√7, 20√7, 144, 60√2, 21√10). A crossed-out calculator icon indicates calculators are not allowed.

Maths worksheet titled 'Fully factorise'. It includes an example: √2y − √50x = √2(y − 5x), followed by four expressions to factorise: √3x + √75, √98 + 4√2x, √48 + √12x, and √32y² + √18xy."

I wasn’t going to, but yet again your post made me get out of the door. Thanks!

“Sir, let me cook” is apparently slang for “excuse me while I try and work this out”

Update: You can now create custom tests on the full-sized version of the KS2 arithmetic generator.

This quick video shows how:

Oops, sorry! I’ll turn the contrast down in future.

In #MathsToday I did this as a starter on estimation.

With the aim of getting pupils to consider which counters are the 'significant' ones.
