What fraction of the tiles are black? How did you get your answer?

With my old state 6th form scheduled for destruction & rebuilding (& an alumni event pending) I've been in 'the records'; however, as I now (in 2024) teach maths my eyes have lingered over an item produced during year 5 at my state primary school. Please excuse rogue SPAG!

Welcome to Mathematical Nirvana.

The double cube has distances between corners equal to the square roots of the first six natural numbers, by the Pythagorean theorem.

If you love geometric designs then the Alhambra is a must. No photo can do any of it justice.

Somewhere in here is a very lovely volume puzzle: the key being the distance between 'slices'?

Not quite to your level of challenge Catriona Agg... The glass viewing roof is made from congruent triangles with side length 1.6 metres. What was the minimum area of glass needed to cut the glass panes from? #geometry

Each time wood for 12 bobbins was cut, one of them was placed on a rack & the rest in a basket. Once there were 3 rows of 4, the rack would be emptied into the basket & the basketful exchanged for a gross being sawn into a tally stick;pay was by the gross. Gross being? #mathschat

Whilst it may be diverting for others to consider whether A23a would generate its own micro-climate, as a maths teacher one might see a great example of something usefully measureable in cubed km. However, #ItsNotThatDeep

Interesting from Dr Laurie Jacques (she/her) and Professor Smudge…

In a session with Anne Watson, ⁦John Mason⁩ and ⁦Dr Laurie Jacques (she/her)⁩ discussing examples of variation - the inclusion of part c) here generated some discussion…

Nice to think about this from Maths Advance at #jointconf24

In NP12, made by the amazing Emma 🐦, we look at standard form as a way of simplifying 'awkward' numbers.

I've started creating some more revision grids, ready for my Year 11s next half term. Hopefully of use to some of you too!
