Numerical coincidences for 2025
There seem to be a lot of numerical coincidences bouncing around concerning the new year 2025. For example, it’s a square number: \( 2025 = 45^2 \). The last square year was \(44^2 = 1936\), …

For teachers:

Looking for a solid extension task? Here is a lovely question that interleaves three different mathematical topics to challenge your pupils.

Find x.

The 2025 Game: arrange the digits 2, 0, 2 and 5 with symbols in between (e.g. +, -, ×, ÷, ^, !, etc.) to make the numbers 0-10. For example, 2+0+2+5=9. How many can you make?

(I just confirmed all numbers 0-10 are possible.)

Take the binary representation of 1/√2, but then interpret the digits (still all 1s and 0s) in base-3. Clearly this number is also irrational. But is it expressible in some kind of closed form?

I'm working on a new talk about big prime numbers - how we choose which numbers to check, primality tests, and what we use big primes for. Anyone got topics or factoids they'd definitely want to see as part of that talk?

(Also, please boost this so that I can find MathsSky, which surely must exist)

We round off the latest season of Mathematical Objects with a chat about Lewis Carroll's Game of Logic.

Our chat inspired me to make the cake shown here as the episode picture, which won the 'best maths in a cake' award at the MathsJam Gathering 2024!

Stumbled upon the Wikipedia article of Grigori Perelman who has achieved many many outrageously clever things, but perhaps most charmingly declined an interview in 2021 by saying

"You are disturbing me. I am picking mushrooms."

Are there any mathematical concepts not currently part of the national curriculum which you think pupils would benefit from learning? Heron’s formula? Pick’s Theorem?

I'm scheduled to give a session at the Joint Conference of Mathematics Subject Associations in April.

Aimed at A level Maths teachers wanting to know about university options, esp. for students without A grades. What do students learn? What careers do they do?

#MathsToday #ITeachMaths #MathsSky
Maths as a university option for students with a range of A-level grades University mathematics varies wildly. Are there degrees suitable for students with B/C/D grades at A-level? At Sheffield Hallam University, we see grades ranging from A to D, and only around a quarter with some Further Maths. We have a strong record of students with lower grades achieving top degree outcomes and developing into excellent graduates with worthwhile careers in mathematical occupations. This workshop offers A-level teachers chance to try out first year curriculum topics, learn how students who don't get top grades get on with degree maths, and hear about careers taken up by graduates.

Another fun arithmetic sum challenge
#iTeachMath #iTeachMaths #MathSky #MathsSky
The sum of a particular finite arithmetic sequence with common difference 3 is 3280. If you were to keep the first and last terms the same, but use a common difference of 4, the sum would be 2480. What would the sum be if the common difference were 5? (You may assume that all of these common differences "work" with the first and last terms of the sequence.)

For teachers:

Agree or disagree?

The history of mathematics should be a part of the curriculum at KS4/5. One valid criticism of British education is that pupils specialise too early. Exploring the history of maths could provide much-needed cultural breadth.

3 by 3 Addition grid. Sum of top row is 359, sum of middle row is 331 and sum of bottom row is 379. Sum of left column is 353, sum of middle column is 349 and sum of right column is 367. Place a different prime number in each of the nine cells of the 3 by 3 addition grid, so that the sum of each row and the sum of each column equal the given prime results.

Three Different Ways to Multiply 18 by 35: Which one do you prefer? Let me know in the comments! #MathChat #MathsChat #MathSky #MathsSky #Mathematics #Multiplication
Three different ways to show that 18 times 35 is 630: Method 1 is the traditional algorithm involving carrying and adding. Method 2 is rewriting 18 as 20 - 2 then applying the distributive property to get 700 - 70 = 630. Method 3 is imagining an 18 by 35 rectangle, cutting it into two 9 by 35 rectangles, and rearranging them to a 9 by 70 rectangle which leaves the total area of 630 unchanged. Which method did you prefer?
