Looking for some ideas. Most of Year 10 are out on a trip. I have a lesson with a handful who didn't go from the whole year group. Last lesson Friday.

In #MathsToday we practiced differentiating polynomials before moving on to start looking at determining if a function is increasing, decreasing or stationary at a point.

Or maybe teach a HL topic in the HL only lesson, but get them to practice when SL are practicing something related? E.g. HL do implicit Differentiation whilst SL practice product rule.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 16/06/2026

Ah, I see. I can see that it would be difficult as the pace for the HL is so much faster and you need to get through the SL content. Could you hold off on stats and probability for IB2 as they don't interact with other topics as much?

Dan Rodriguez-Clark @interactive-maths.bsky.social · 16/06/2026

Not something I have done. If I had to, I would try to get it scheduled so all students could attend all lessons on their timetable and then you can let the SL students know when they don't need to come.

Decided to make the focus of Year 7 Algebra on manipulation, and leave solving equations until year 8. Picked out 2 or 3 key skills for each year group to focus retrieval starters around.

In #MathsToday we had a productive meeting where we discussed changes for the curriculum next year.

IB Maths Teachers As students work towards the exams in May, they will probably be doing full sets of past papers. Help them understand the weighted totals for grade boundaries with this tool where the input paper marks. tutor.interactive-maths.com/ibdp-maths-g...

An online tool with the input
Course: AAHL
Year/Session: 2024 May TZ1
Paper 1 Score 65/110 Paper 2 Score 53/110 Paper 3 Score 27/55 IA Score 12/20

And the output
Paper 1 Weighted: 17.73/30
Paper 2 Weighted: 14.45/30
Paper 3 Weighted: 9.82/20
IA Weighted: 12/20
Weighted Percentage: 54
Grade: 5
Points to Next Grade: 8

Do share this with your exams team. Hopefully helpful for them to manage the different times for exams this mock season.

Should work on an iPad, but I don't have one to test it. Let me know if not. I don't remember seeing any official stuff on desmos. I have used it to put bits together for our department.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 26/01/2026

I used this successfully today to teach solving a quadratic equation when you have draw a line on a given quadratic graph. Being able to write the equation next to the graph was really helpful.

000

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

I will take a look at how I can change that.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

The id is the last part of the website address. You just copy that part. But I can update it to take the full link.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

You can either use the blank one to create live in the lesson, or load a saved desmos graph. Not compatible with desmos (now amplify) classroom.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

I am not going to use it for labels in reality. It is useful to be able to draw on a graph when demonstrating.

110

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

That is the topic I am teaching next week that made me want this! Though I will just type a live equation of a straight line into the desmos directly.

000

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

Whilst I get your point about the labels, and I can do that, a lot of teachers don't know those more advanced features and they do require a bit of learning that some just aren't up for. This is slightly less 'tech advanced' I think. But I get your point for labels, I was more thinking demos.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

2. In class I wanted to write a question on the board for students to see with the desmos showing. I know I could use the note section for this, but personal preference. 3. We have TV screens instead of projectors on boards, so I can't write on them. I use graphic tablet to annotate live a lot.

200

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

I had three personal reasons for it. 1. When I record a video using desmos, it is helpful to be able to use my graphics tablet to write at the same time as seeing the desmos activity. Especially when they are embedded without the equations showing.

110

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

Yes. The ink is separate to the desmos graph, so you can change the desmos and ink stays. You can then add more ink.

100

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

Not at the moment. Do you mean a second graph to appear side by side?

100

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

You can either start with blank Desmos file and build it up live, just like you would in Desmos. Or create an interactive Desmos file before the lesson, and then load it using the unique ID generated by Desmos. You can then annotate with the pen tools, or add a textbox.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 25/01/2026

Ever wanted to annotate on a Desmos file? I have a new free tool that allows you to do just that! Useful for #MathsToday www.interactive-maths.com/desmos-annot... @mathsjem.bsky.social @studymaths.bsky.social @themathsbazaar.bsky.social @colleenyoung.bsky.social @suzannerelou.bsky.social

I think my question generators are really useful for creating quick questions (biased!). You can project and get as many as you want, turn them into worksheets, bingo, other activities. generator.interactive-maths.com

I might not be able to make all 5 online times (parents evening). Is it possible to get recordings to watch if I miss one? Don't want to sign up if that will be a problem.

Mocks coming up? I have a tool that helps get the timings straight when there are multiple exams, and extra time thrown in too. In IB we do 30 minute and 5 minute announcements, not sure about GCSE and A-Level? Can either be on screen or printed like this. tutor.interactive-maths.com/exam-timings

A table with columns for the time, examples, students affected and announcements for running exams. It shows the regular time announcements and 10% and 25% extra time announcements for two exams, and the timings for these announcements.

In #MathsToday we looked at the integrating factor method for differential equations. Lovely to bring in some of the other integration methods too.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 04/01/2026

No, that is a bit crazy. I have it all on the cloud, on my hard drive and an external hard drive, just to be safe!

010

Dan Rodriguez-Clark @interactive-maths.bsky.social · 04/01/2026

I have everything on the cloud, but I use a USB for two reasons. 1. It is easier to quickly open files without the need to log in to my Google account. 2. We can print straight from USB

A couple of ideas for Christmas drawings based on this Desmos activity.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 16/12/2025

NEW TOPIC - Similar Shapes Choose from which measurement to be known and which to be unknown from lengths, areas and volumes. As with all questions, project on the board, turn into a worksheet, or treasure hunt, matching cards, bingo, or more. generator.interactive-maths.com

Four questions on similar shapes where you are given two shapes and some measurements and have to calculate a missing measurement.

In #mathstoday with year 10, I am quite happy with this set of questions I came up with on solving quadratics with the formula to get exact answers.

Dan Rodriguez-Clark @interactive-maths.bsky.social · 15/12/2025

Created a set of matching cards for my year 11 class in #MathsToday to practice finding quadratic functions from graphs when given the vertex or the roots. generator.interactive-maths.com/maths-questi...

I had to move the desk around when I moved into my current room to make it possible. I would prefer a standing desk though.

I use a graphics pad every lesson. I have a document of 8 blank pages saved to my desktop. Open it up in edge, write on it like a whiteboard, then save a copy at the end of the lesson and upload for students.
