Merry Christmas! I’ve enjoyed the @mscroggs.co.uk puzzle advent calendar - prizes to be won if you complete the puzzles this year www.mscroggs.co.uk Something else I’ve enjoyed being part of: the Mathematically extra-complicated Secret Santa 2025 — @tomvii.bsky.social’s video: youtu.be/4pG8_bWpmaE

I've just completed all the puzzles in the mscroggs.co.uk Advent calendar! My favourite puzzle was Day 8. #ITeachMath @mscroggs.co.uk

I've just completed all the puzzles in the mscroggs.co.uk Advent calendar! My favourite puzzle was 17. What looked like a very long counting exercise made much simpler with a little insight. Thank you @mscroggs.co.uk !

I've just completed all the puzzles in the mscroggs.co.uk Advent calendar! My favourite puzzle was day 21. Took some hard thinking. Once again @mscroggs.co.uk making me do combinatorics. And of all the puzzles how was day 12 the only one I got wrong first time around?

This year's Xmas Puzzles (that we played a small part in helping put together) are now available at thexmaspuzzles.com. Enter your solutions by 8pm on 18 January for a chance to win a donation to a charity of your choice. Happy puzzling!

Who's staying up to do some #MidnightMaths this year?

This is great fun, even though I am stuck on door 21. #MTBoS #maths

#NetflixChristmas Reviews 2025 #3: A Cinderella Christmas Ball. Dance instructor teaches Sir Prince King II to dance then finds love and her father or something. 🎄💃❤️😴🎄/5

#NetflixChristmas Reviews 2025 #2: Haul Out the Holly. Single woman returns to parents' huge house for Xmas. HOA insists she decorates the street. Instead of leaving, she falls for HOA president. Painful. Talent wasted on the script. Clearly summer. Is it a spoof? Took me 3 days to watch. ☀️⚪️🍿💅🚯/5

#NetflixChristmas Reviews 2025 #2: Haul out the Holly. A Hallmark Christmas film, but thankfully not one of the really cheap feeling ones. Has the other one from Mean Girls in it, who obviously goes to a small town to celebrate Christmas. 🎄🌨️📜🌨️🎄/5

#NetflixChristmas Reviews 2025 #1: Champagne Problems. Idk why but this reminded me of Emily in Paris even though main girl is competent at her job. Maybe it's because of the scenes where French people talk to each other in French. Anyway I liked it, nice Christmassy escapism. 🇫🇷🍾🥂🌲🎄❄️/5

#NetflixChristmas Reviews 2025 #1: Champagne Problems. Workaholic American goes to Paris; gets involved in a champagne business; falls for a Frenchman. It’s Emily in Paris + tinsel. Starts weak but side characters improve over time and I actually laughed at points. A strong start. 🇫🇷🥂🇩🇪🚄📚/5

Me, @pecnut.bsky.social and @aaclarke4.bsky.social are once again watching and reviewing a ton of #NetflixChristmas films this year. Check out docs.google.com/spreadsheets... if you want to play along.

Maths teachers: if you're looking for an end of term Christmas lesson, there's an A4 pdf of the Christmas card linked from mscroggs.co.uk/blog/121

The first 8 doors of the mscroggs.co.uk puzzle Advent calendar are open. Still plenty of time to catch up if you've not done them all yet. If one puzzle per day isn't enough, this year's @chalkdustmag.bsky.social Christmas card is now available at www.mscroggs.co.uk/blog/121 with 12 more puzzles.

I ordered some A4 paper so that I could print off my copy of Puzzlebug #1 from @mscroggs.co.uk in the proper format. A fun set of puzzles just right for a holiday stocking. www.mscroggs.co.uk/puzzlebug/

Text from my 13 year old daughter this morning as she is stuck home recovering from major knee/leg surgery. "what's the website with the math advent calendar so I can start?" sent her the link to one of our favourite December traditions. Thanks @mscroggs.co.uk www.mscroggs.co.uk

It's December so apart from #AdventOfCode it's also time for @mscroggs.co.uk maths puzzle advent calendar. Day 1 and already I'm forced to do some combinatorics. It's starting early this year! www.mscroggs.co.uk

“It's nearly Christmas and something terrible has happened…” Time for the famous @mscroggs.co.uk www.mscroggs.co.uk advent calendar! Good fun — but am I too busy, or will I keep it going this year? Only time will tell!

@mscroggs.co.uk found your solutions to the partridge puzzle #mathsjam zenodo.org/records/1705... ...do you need my handler to help refactor your code?

my 13 year old daughter was just talking about this the other day, she's excited to work on again... I think this will be year 4 doing it and year 3 doing it together.

I'm home from #TMiP25. Was great to catch up with a lot of old faces and meet many new faces. I'm very very tired, but not the most tired I've ever been after working on an event with @steckl.es (see 24hourmaths.com)

Printed this puzzle to do at #mathsjam yesterday. It's a great puzzle mathstodon.xyz/@OscarCunnin...

Having a clear out of some old computer equipment that's been cluttering up my place for a couple of decades. It's absolutely SPARCtastic. All free to a good home. r/vintagecomputing are all over it, but if any of my friends here want something then just ask.

I'm very glad that the Switch version of Final Fantasy 12 has a 4× speed mode
