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

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?

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.

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

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

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

After they got good at decomposing numbers, I used this to introduce the idea of finding LCMs efficiently.

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

Any good ones to add to my list?

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

This was his method.

In #MathsToday I set my Y9 this little "bonus homework" after introducing prime factors. Wonder if they will spot the link?

Short but very hot baseline set today.

@bennewmark.bsky.social recognise this run?

A slow 6.5 km struggle after indulging too much at a bbq last night. Feel better for it now though.

10.5 km and got back to “Dad your T-shirt looks like Mickey Mouse!”

Good effort!

I just finished a 5 km ahead of a big gardening session today.

My watch split the run up into two because you spent so long whinging about your “injury”.
July 25, 2025 at 9:52 AM
Ha, great times, we should do it again.

Just finished a 10.5 km. Bit hot.

In #MathsToday we played this. A sneaky way to squeeze in some revision on multiples and lots of fun.

In #MathsToday we made a double-decker-dodecahedron.
