Came across a guy on TikTok who creates tools for teachers. This site is great for creating diagrams. Best one I've come across. Will be using it for lessons and assessments. mathfigures.com E.g. angles on parallel lines in the pictures. @mathsjem.bsky.social #MathsToday

We had open morning in school yesterday. I used the selection problems from Axiom Maths as one of our activities, was great to see so many children try them out. Felt like we created some real interest in Maths Circles for prospective students #MathsToday

I sent out a survey to all Y7 students earlier this week, I did not expected the results to cause me to consider the philosophy of life and maths as much as this response did #MathsToday More generally, I'm interested to find how our student attitudes to Maths may change as Y7 progresses

Very interesting and informative report from the Sutton Trust around how opportunity for students is affected by location, gender, background. Was surprised by some of the trends shown in the report. Would recommend anyone in education in the UK reads this www.suttontrust.com/our-research...

Been finding it particularly useful for A-Level stuff like this - would take a very long time to make questions myself.

Saw something recently about AI making an incorrect quadratic graph. Gave me an idea to use AI to create "common sense" check questions. Students often don't check if their answer makes sense. I try to embed this in my teaching, this will help. Started with quadratics #mathstoday shorturl.at/Y7jfq

I give a set of instructions about what I want, and Gemini does most of the work itself. Here is a link that you can use - just type in the type of questions you want, and it should format nicely gemini.google.com/gem/1KWCEBy4...

I asked Gemini to make a pre-req check for eqns of horizontal/vertical lines, starting with plotting coordinates. Gave back some questions I wouldn't have thought of. Will be great discussion/thinking questions for my group. Finding lots of use for AI as a partner to plan lessons. #mathstoday

This looks great, thanks for sharing! It would be helpful to have a pen tool that draws straight lines, too, if that were possible. Thinking of using this to show how to solve quadratics graphically

I've sometimes managed to fix it by telling Gemini to use an Edexcel exam paper as a model for how the diagrams should look, but it's not great at the angle arcs generally

Hello, glad you found it helpful! These look great I'm not sure the best way to link it in Google Slides, as I don't use it. I've been saving the files on my computer and linking them into my PowerPoints using hyperlinks. I don't know if Slides might work in a similar way or not

I take your point, but most things we consume today have an impact somewhere that we don't want to think about. AI has an energy problem, which will have to be solved for the companies to be profitable. Being hooked may well be true but could have been said about the internet.

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! #MathsToday

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.

I've tried LaTeX with overleaf a little. I've been experimenting with both web development languages and LaTex to see which I prefer to generate worksheets. I'll try both some more before I decide which to stick with! Thanks a lot for this, will definitely look into this with Visual Studio/an IDE

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 #MathsToday #ukmathschat
