It's been a few weeks since any updates, but here are some new resources from this week's teaching of solving equations:
✨Linear equations with fractional coefficients practice grid
✨Solving quadratics by factorising sort it out

Every time I visit my mum I’m always reminded of these mathematical placemats.

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.

A silly bit of interweaving or a useful task?

A brain dump of mathematical misconceptions.

Which of these might be avoided through careful teaching?

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:

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

Drawing attention to important decisions that need to be made.

In #MathsToday (ish - probably last week actually) some activities with Surds.

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

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

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

In #MathsTomorrow I'm going to try and develop a sense of why we round numbers.

Any good ones to add to my list?

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.

In #MathsToday I gave my 7yo the calculation in the box at the top.

This was his method.
