For any Australian Y11 Maths Methods teachers, I've collated all my lessons for the year and shared them on TES. We used the Nelson WA Textbook, so they're aligned to those exercises. Hopefully it can save someone some time! www.tes.com/teaching-res...

For those who use the Casio ClassPad II calculator (most of Australia), I recently created this booklet to help my Year 10s. It is self-paced and explicitly teaches students many important calculator skills that tend to be "assumed knowledge" in Y11 ATAR Maths. D/L free: www.tes.com/teaching-res...

This got me thinking! I like that you used easy questions to introduce each concept. It would be much harder if you went straight to the big guns. I think I made some mistakes as the picture is a bit whack. Number 8 is the only one I couldn’t get an answer for so I’ll have to have another go later!

Introduced my Year 7s to solving equations this week. Made a worksheet to focus on the single skill of identifying the inverse operation for each one-step equation. It also got students used to writing the operation on BOTH sides. #Mathschat #MathsToday #AusMathsChat

Colourful worksheet with four columns. Title is "write the operation applied to both sides".

Was an absolute treat to listen to Craig Barton and Ollie Lovell at the Becoming a Better Maths Teacher today in Perth. Managed to snag a photo with the man himself! We had a deep dive into atomisation and am even more excited for @krisboulton.bsky.social’s book to come out now.

Now to come up with a question for students to prove this using vectors!

In #MathsToday, this week I've enjoyed playing a new game I've been working on: Duelling Mathematicians! interwovenmaths.com/duels Two players at the board take turns answering maths questions, with chess clock-style timers. The sounds/music are the best bit! More topics being added soon...
