Looking for simple to use, customisable axes or graph paper?
I've made a couple of tools for this.
Designed to be printed or pasted into PowerPoints etc.
The snipping tool (win+shift+s) is your friend.

Teaching Vectors to Y12 tomorrow. Wanted to break down some of the individual skills into short activities as a scaffold/ to support fluency. Generated these activities to display after the explanation. Very impressed with what Gemini has generated

In #MathsToday I've been using the OAT Maths resources to teach Circle Theorems to year 11. Finding them fantastic for scaffolding and supporting student understanding
The maths Conf session back in June from @jemmaths.bsky.social was a great introduction to using the resources

I am still finding it incredible how quickly AI can produce high-quality questions for my lessons. These are fantastic for displaying on the board and clicking to reveal answers as students work, a few at a time.
Took 2 mins to make and they sequence exactly as I wanted!

Some schools do a test at the end of every topic. For some, this can mean 10 tests a year, not including end of year.
This may be trying to game the testing effect, but this isn't increasing outcomes as much as you may think.
We test three times a year. open.substack.com/pub/joel1201...

More Testing ≠ The Testing Effect: What is the Testing Effect?
The Testing Effect enhances long-term retention through retrieval practice, not frequent testing. Completing more tests doesn't mean you'll get the testing effect.

Been finding it helpful to get GCSE coverage of topics easily (as quick recaps) with AI-generated questions, rather than snipping from various sources. Pythagoras example here
The flexibility, for example, of asking for one question to be changed in a certain way is great
