In #mathstoday we are using special right triangles to help find exact values for sin 15 and cos 15 without a calculator #geometry #iteachmath

In #MathsToday Oxford Mathematics have opened school applications for the pilot of our new free GCSE Maths mentoring scheme aimed at getting pupils from grade 7 up to grade 8 or 9 (or equiv.), with Oxford students as mentors. Now we just need schools to sign up! www.maths.ox.ac.uk/outreach/oxf...

Thank you for writing up your day! I was sad to miss this one, it looked like a great line up (as always!)

Highlights from my workshop today:
These were the questions that the participants found interesting from papers abroad. What do you think? #MathsConf40

New: a quick post about yesterday's #mathsconf40

Properties of triangles for Year 7. #mathstoday #mathsteaching

Some tasks to round up a unit on speed, distance and time for my foundation GCSE class. #mathstoday #mathsteaching

Now looking at how to stretch our KS3 students, so we're off to @mathsjem.bsky.social! #Mathsconf40

So lovely to see @mathsjem.bsky.social giving a shout out to @draustinmaths.com whilst listening at #Mathsconf40!
There's also a few gems that were great reminders!

A slide titled Target Answer Challenge. A green banner in the center reads Design two different math problems where the answer is 2x plus 1. Below the banner are two colored boxes. On the left is a red box titled Linear Relations with the instruction Design a problem where the goal is to determine the equation of a line. Underneath it says Think about: Constructing a problem using two coordinate points, or using a point and a given parallel or perpendicular line. On the right is a blue box titled Differential Calculus with the instruction Design a problem where the goal is to determine the derivative of a function. Underneath it says Think about: Finding the first derivative of a second-degree polynomial, or the second derivative of a third-degree polynomial.

A problem to start calculus class on Monday. We're not to integration yet, but I want to start nudging student thinking in that direction. Plus a bit of retrieval practice and creative thinking/problem solving. #ITeachMath

I really like "Method 3" of how @blatherwicksam.bsky.social solves AS Further Maths inequalities. #Mathsconf40

I like this trio of questions that Shamim Brek has presented here, will be doing this with my mixed tier group on Monday morning #mathsconf40

@stephenfroggatt.bsky.social sharing the first equations (written with an equals sign) in history from Robert Recorded at #mathsconf40

This is coming up at a perfect time.
It's almost time to review our scheme of work (I made lots of changes last year) so it's nice to see how other schools (such as here from Joe Berwick) does his.
And then he covered the large data set - which I'm stepping in to teach for Monday! #Mathsconf40

Will upload solutions over the weekend

I’ve been thinking about fractions

Gave this warmup question to my class today. Students had to think carefully about the function and what x represents in each statement. Great discussions. @studymaths.bsky.social #ITeachMath #MathSky

Somehow it has never occurred to me that I could just write out the sequence again at the bottom

I like how you’ve laid out the working. This is my favourite method too, but I always end up making a mess of writing it down, because I get tempted to overannotate the sequence in the first line

#Mathstoday
Year 11 had a reteach lesson today, last year I taught quadratic sequences differently, changed methods this year which really worked well for my year 10. Decided to teach the year 11s since they had completely forgotten the other method. They really preferred it.

Oh no! That interactive map was great, I hope there’s a replacement somewhere

We've got a really exciting project running next year - a pilot of using graphical calculators in AQA Level 2 Further Maths.

Schools get PD, resources and a loan set of calculators for a year.

Places are strictly limited but you can apply now!

A linear scheme of learning for A level Maths based upon pedagogical principles Background When A level Mathematics became linear (decoupling of AS and removal of modules) it presented an opportunity for the teaching of A level Maths to be released from the constraints of modu…

The rationale for my A level maths scheme of learning

An educational graphic titled Which One Doesn’t Belong. The image asks viewers to find a reason why each of four mathematical graphs does not belong, using a provided list of calculus terms. The four graphs are arranged in a square grid. The top-left shows a periodic cosine wave oscillating between positive and negative one. The top-right shows a standard upward-opening parabola with its vertex at the origin. The bottom-left shows a rational function with a vertical asymptote at the y-axis, where both sides of the curve approach positive infinity. The bottom-right shows a cubic curve that passes through the origin and increases from the third quadrant to the first. To the left of the graphs, a list of suggested vocabulary includes Domain and Range, Continuous and Discontinuous, Differentiable, Increasing and Decreasing, Concave Up and Concave Down, and Point of Inflection.

This "Which One Doesn't Belong" warm-up question generated some rich student discussions today in Calculus class. The word bank was helpful in nudging them to include curve sketching terms in their justifications. #ITeachMath #MathSky #WODB

I was going to recommend these as well - they are great, and there’s one for almost everything!

Maths Teachers — If you could add a feature/resource type/section onto Mathsbox that would save you time or improve your lessons, what would it be? 👇

Would love to hear your ideas.

I gave my calculus students a roller coaster project to practice continuity and differentiability. It was a good learning experience for both me and my students. Planning on some revisions for next year. #ITeachMath #MathsToday pbbmath.weebly.com/blog/the-rol...
