In #MathsToday we did a task that creates the need for equivalent ratios.
We used counters, the bottom row is where the real fun starts.

I'm including SCG in a presentation next week on Inquiry routines / problem solving strategies.
Love this (John Mason)
SPECIALIZING means choosing examples
● randomly, to get a feel for the question;
● systematically, to prepare the ground for generalizing;
● artfully, to test a generalization.

GCSE maths anxiety is rising, and teachers are feeling the pressure too. Maths Revolution shares simple, steady approaches that help students build confidence and stick with it. A reassuring read for anyone teaching GCSE this term.

For some, they are a meaningless scourge. For others, they are a vital accountability lever that provides insight into the lived curriculum.

Are "book looks" a waste of time?
Book looks and work scrutinies are a staple in many schools. But can they actually tell us anything about teaching or learning?

Raises the question about distinction between mathematical skills and topics (even those terms warrant better definition). The skill/procedure is proportion, but the topic is it's own. Much like percentages.

Pie charts - worthy of being called a topic on their own in a curriculum, or just an application of direct proportion?

Two regular hexagons inside a rectangle. What fraction of the rectangle is shaded?
I found this #geometrypuzzle in my sketchbook - I drew it last June, but I’m pretty sure I never got round to posting it. Better late than never!

Here is an even more generic version, and a nudge towards a more efficient ratio table approach.
The ratios are now blanked out which is a nice bonus of the table approach.

Set 1 and the @goteachmaths.bsky.social Mark Maximiser showed us that completing the square was a huge gap…

The "blank is best" approach to slides is a powerful tool for responsive teaching.

Yes, it's based on my work on the Proof Materials Project (2004 - 2005). Here's an extract from the report, arguing for taking a generic approach to the 'matchstick squares' task.

Interestingly, I think there are also times when the opposite approach is worthwhile!

This thread is absolutely perfect for stuff I’m trying in my classroom these days. I’m taking part in a “Developing Mathematical Thinking” project with University of Dundee and we are looking at things like this. Will try out lots of these. Did the 4 digit palindrome one. S-C-G would’ve improved it.
