Just appeared online recently. Games are widely used in mathematics lessons...but how does what the teacher does enhance the learning from a game?

If you are the right place on the bank, you can see that some of the supports are further apart than others. Where it got fixed.

Questions about what does "anywhere on earth" mean. If you submit on the specified day before midnight (like Cinderella) in the time zone where you are, then you are fine. Of course, if you want to imagine you live in the middle of the Pacific Ocean...double check your calculations!

The fifth time is indeed the charm. Writing it all up neatly and nothing has come unstuck! The diagram on half a sheet of paper from several months ago, which I had convinced myself only needed fleshing out a bit when I got around to it was, in fact, not the charm.

Ms 18 thinks it is very impressive, until I was unable to pick out the square that I made...

I am now up to the fifth time that I think I have proved this thing. Ms 18 (who is the same person that I have called Ms 19 recently in error, it being a new year(!)) is a maths major and she has watched the process of a mathematician trying to establish something for most of her summer break.

My daughter: Mum, what day is it today, and what do you think I got at work?

Me: Shrove Tuesday...Pancakes? (Seemed unlikely, but remotely possible.)

Daughter: It's Lunar New Year, and I got a "red packet".

I think I have a proof of something for a paper I have been writing. However, this is the third time that Iโ€™ve thought this, so Iโ€™m more hopeful than triumphant.

There's a whole academic integrity community that I was part of on the old platform (delete X here). Unfortunately, it has not migrated here. The short answer is that absolutely universities should (and many do) have policies about this.

During a faculty debate this morning on the topic of using AI to help grade assignments, I pointed out that students should have the right to opt out of having their work uploaded to an LLM (or any external system, like Turnitin). Does anyone know of any cases or laws or policies that support this?

Day 6 of the math-art class Iโ€™m leading. The main activities: lunch and share outs with the math and music class, and setting up an art gallery and pairs of our kids each showing their art pieces and doing an art project with 3 kindergartners. Each pair created their own lesson plan! #mathart #mtbos

I started this project twelve years ago, and today I hold the result in my hand. Itโ€™s a book that combines bead weaving with math called, โ€œBeading with Algorithms: Cellular Automata in Peyote Stitch.โ€

This book is the first of its kind, a recipe book of algorithms for making pixel art.

My go-to recently on these 40 degree days is salade nicoise, because even the selective eater will eat some parts of it (e.g. the white part of the egg(!)). And I do the potatoes and beans in the microwave to generate the least amount of extra heat. But it's not a last minute meal.

Can't quite tell - are those embroidery frames in the top right of the hitomezashi photo? Did you stitch some?

Lovely morning picking raspberries at Kinglake Raspberry Farm with Ms 19. It's a bit of a summer tradition for us now. Much later than most years. (Always get a smile from other people's kids who spot a wombat hole, of which there are many, and think that they might spot a wombat.)
