Got to talk to all of my maths colleagues across Astrea Academies tonight about ratio tables across the curriculum 😍😍😍
Total privilege and so excited to see how it impacts teaching and learning for our scholars 🤩

Had a Year 11 intervention class today with only 6 students in because of a mock exam running.
Set 1 and the @goteachmaths.bsky.social Mark Maximiser showed us that completing the square was a huge gap…
So over to @studymaths.bsky.social MathsBot we go for some algebra tile goodness!

I used this template slide to introduce sharing in a ratio with Y9 in #MathsToday (yesterday)
The "blank is best" approach to slides is a powerful tool for responsive teaching.

What’s everyone’s experience of students managing their maths exercise books? Loose worksheets are a problem. We’ve tried gluing in but then it can get costly. We’re currently trialing hole punching books and using treasury tags but students struggle with the dexterity needed & organisation. Ideas?

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

There are 3 ways we can improve provision at Key Stage 3.
First, stop treating KS3 as a warm-up for 'serious' work at KS4.
When we do that, we lower the intellectual bar, often without realising it.

A friend of a friend is doing a PhD, focussing on what teachers know and understand about gender diversity in the context of secondary & college education. Her research aims to determine what training (if any) teachers feel they need to be able to work with gender diverse students. (1/2)
