5 weeks of summer done, 2.5 to go! Might be time to start pondering things for Year 2 - first up, unpack all the boxes in the study so I can get to my desk.... #StillInHolidayMode

but going back to the original question about whether they'd been penalised, as long as it doesn't go off the grid I would suspect that it was fine

When I was a teenager, it was very firm that you DID extend in Science or Maths and did NOT in the other but I can't remember which way round it was....

I've not marked any stats papers that have had this in it so I hesistate to lean either way but my preference is not go beyond the max/min of the data set and to repeatedly have the conversation about the dangers of extrapolation (as that's always a one marker with my current exam board)

Biggest perk of moving home last summer, my first year of teaching in NI is now complete!

Now for a fabulous 7.5 weeks of annual leave :D

It's human nature to remember the good bits & forget the rest, especially when you will have had such a big impact on your students! I always talk glowingly about my 1st school for what it taught me but the more experience I get the more I appreciate how utterly complex & challenging it really was.

I wouldn't say it's typical of all schools, but it's definitely typical of some.

3-6 months of "just looking" and then when we found one we really liked that jump started the seriously looking each time.
Completing a sale is taking forever now though, no part of the system seems to move fast anymore.

introduced the idea of zero pairs to my classes last week whilst discussing calculating across zero, today when we were adding and subtracting negative numbers using double sided counters they picked it up SO quickly.

Love it when a plan comes together!

I wasn't pleased when the modular system was ditched in England but I do miss the clear and consistent expectation on teachers and students!
I wouldn't go so far as to say that I think it's better, but I do miss it

It is! And so few have shared what they do online that I'm not getting a sense of what is reasonable/achieveable/typical within the system.
Another reason why it reminds me of 2017 πŸ˜†

I'm constantly surprised at how little depth there is in M2 and M6 compared to the Foundation tier in England. Love the addition of binary though!
The modular system vs three exams in May/June of Y12 makes sequencing the curriculum more challenging than I'd like. M2 should be a non calc exam!

Been ruminating on how to properly get to grips with the NI CCEA GCSE Spec and half way through building a revision website for my students as my holiday project I realised that I did the EXACT same thing in 2017 when the KS5 Specs changed in England! πŸ˜†

Question 1 from the 'Wrogn' paper. The same exam question is on both sides of the page, but on the left is a solution containing a mistake. The right side is blank to allow students to write their corrected answer.

In #MathsToday, Y13 FM were introduced to their first Further Stats 1 'Wrogn' paper.
They had to identify and correct the error in each answer to get a set of model solutions. I felt it worked nicely as a way to gently introduce FS1 past papers, which we only finished the content for last week.

In #MathsToday with Y8 I used @taylorda01.bsky.social's IDQ's on Expanding Brackets as a Do Now, leading to double brackets...and with Y9 I used a Don Steward task on Simplifying Surds, and ended up talking about Exact Trig, Pythagoras, Hipassus, and the Unit Circle. #EduSky #MathsTeachers

@inquisitivetea2.bsky.social not to dox myself but seeing you retweeted into my timeline is a delightful blast from the past!

Hope life has treated you well since our time at NCA (I was a trainee 2012/13, then stuck around in maths until 2017)

Totally empathise with Jo's feelings around edutwitter and BlueSky. Miss the old days and haven't got the hang of Bluesky yet.
LOVE @catrionaagg.bsky.social & @mathsjem.bsky.social topic maps in this Gems Post though - sparked some more ideas to throw into our curriculum review....

Couldn't work out why I had to have a 4 hour nap this afternoon and then remembered that I had 80% of fifth form sit their CCEA GCSE completion paper on Thursday... HoD tired is something else entirely!
