It’s Day 3 of #CalculatorCrunch and today’s puzzle is called 7-digit Numbers. We’ve given you three starting values of 10, 250 and 5,000. Using the operation times and brackets, can you create expressions with 7 digits, more than 7 digits and fewer than 7 digits? Visit buff.ly/npVOvTf for more.

After school further maths getting stuck into some trig equation solving. Planned a really precise approach for yr12 (manipulatives, laminated write-on graphs, small steps that move v quickly) and it’s worked really well for year 10 L2FM too! #MathsToday

Inspired by @mathforge.org at the Easter conference, today I started teaching Y9 trig by using similarity to reference triangles. #MathsToday I thought my class would need extra scaffolding so we started by using one triangle in lots of orientations…
Two triangles, both with angles of 25 degrees and 90 degrees. The first has a hypotenuse of 1, and an annotation reads “we call triangles with a hypotenuse of 1 'reference triangles'”

Underneath the triangles is a ratio table with multipliers drawn on both horizontally and vertically, in order to find a missing length on the target triangle. The same reference triangle, and another similar triangle. This time, the ratio table has been used to find the hypotenuse of the target triangle by dividing by the vertical multiplier. The same reference triangle, with a similar target triangle in a different orientation. The same reference triangle, with a similar target triangle in a different orientation.

Started pythagoras with Y9 in #MathsToday. I really like these questions that start with areas of squares, and gradually remove the squares until it’s just side lengths. Would highly recommend @drrowlandson.bsky.social’s blog post about this approach ponderingplanning.wordpress.com/2022/10/15/t...
Where possible, find the missing values. (If it's impossible, say why.)Each diagram shows three squares joined together.
Find the area of the blue square.

Some #MathsToday from the second A Level Pedagogy work group meeting with 10 other teachers from Essex. The theme was using graphing technology - I particularly liked learning how to use a graphical calculator! This task was a fun one. How would you answer? #ALevelMaths
Which one doesn't belong?
Give a reason why each graph might be considered the odd one out.
What is the most obvious reason you can give in each case?
What is the least obvious (but still justifiable) reason?

I used to encourage students to highlight F or Z shapes for parallel lines questions, but today I just told Y9 to highlight the transversal. It’s an easier first step, and they were almost always then able to immediately see what to do next. Also, I love these MathsPad questions! #MathsToday
6 questions of the form:

On a copy of this diagram, mark the cointerior/corresponding/alternate angle. 

The solutions have been drawn on, with the transversals highlighted in yellow. 

6 diagrams with some angles given, including ones not needed to answer the question, and one missing that has to be found. They have been answered with the transversals highlighted in yellow.

In a letter in the new issue of Mathematics Today, which just arrived, I talk about the range of degrees offering maths and how in my experience it’s a great option for students with lower A level grades. AMSP videos are here: www.youtube.com/playlist?lis... #MathsToday #UKMathsChat #ITeachMaths
Promoting Inclusive Maths Degrees 
I appreciated Cathy Hobbs' article [1] about the work the IMA is doing in response to the paradoxical situation that Maths is the most popular A-level subject while some university courses with lower entry tariffs are under threat due to reduced student interest. A-level grades do not only represent achievement, they also encode a number of extra-curricular factors connected to socioeconomic background, meaning there are extremely capable mathematicians who are not getting the full chance to thrive in the A-level system and might be locked out of becoming professional mathematicians as a result.
One issue is the advice students are being given. Maths teachers have told me they advise students they shouldn't consider maths at university if they aren't on track for an 'A' in A-level Maths, and one said he tells students they can't consider degree-level maths if they aren't taking A-level Further Maths. This stems from a perception that maths is a hard degree, so the advice to study a different subject like finance comes from a kind place.
There are also issues with the perception that maths is a degree that leads to a research career but fewer employment options.
I suspect that some teachers experienced a highly-theoretical degree designed for students with A*/A grades and this is their perception of maths at university. Actually degrees vary consid-erably, with many lower-tariff degrees designed with enhanced student support, a curriculum focused on mathematical practice, and opportunities to develop career skills for the wide range of careers to which a maths degree can lead.
At Sheffield Hallam University we typically see A-level Maths grades ranging from A to D, and only around a quarter of students have some Further Maths. We have a strong track record of students with lower intake grades achieving high quality degree outcomes and developing into excellent graduates with worthwhile careers in mathematical occupations. A recent p…
