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.

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?

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.

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:

In #MathsToday I did this as a starter on estimation.
With the aim of getting pupils to consider which counters are the 'significant' ones.

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.
