We've found that schools are quite disorganized when we try to find a place for a homeschooler to take a test.
An unrelated AMC8 question: Are the AMC8s from >10 years ago known to be somewhat easier than the modern ones?

... it's definitely a lottery school.
What is a "lottery school"?

I'm interesting in signing up dd6. Her birthday misses the state cut-off for 1st grade by about 2 weeks, so she's technically a Kindergartner but academically more 2nd-3rd grade. Is there any reason I shouldn't just call her 1st grade for the sake of the test? Like, is there a benefit in "red-shirting" her? I'm thinking probably not, but I don't know if there's something I haven't thought of.
She can register as grade 1 this time, and again next time.

No, but if you go through the process of registering, you can see what the options in your area are then (or you can come back later to complete the registration).
I know, but it's very inconvenient. With the testing centers being so few and far between, it's always been much more convenient be able to go straight to the "centers" page
http://www.mathkangaroo.org/mk/centers.html
to quickly see if anything remotely close has been added.

This is Australian? Does it matter? Do their grades correspond to US grades?
I guess it's open to anyone anywhere. Just use US grade.
FWIW we "splurged" the $2.99 for the practice materials. It was US$2.99, but the questions have Australian/English spelling (e.g. colour, litre etc), so there's the international aspect.

We'll wait until December, to minimize driving distance.

Hmm, would you sign your kid up by age or current level in that subject?
By what grade my kids would be if in school. Same as for all other math contests like Math Kangaroo, Mathnasium Trimathalon, AMC8.
I agree. Just use the grade they are in, or would be in, in school, based on age. They compete against their age/grade peers, even if they are accelerated in math. Plenty of other contestants are accelerated too. (I'm sure you can do a higher grade if you want.) I've never seen this contest before, so I don't know the difficulty level, but I assume there'll be be some tougher questions to separate out the top contestants. Anyway, we're enrolling in grade based on age, and telling DS it's low stakes, just have fun, but avoid careless mistakes.

Everyone is focusing on the work-ethic issue, which is important. Lack of effort is a concern. But that's not what this describes:
He will throw tests for qualifying for competitions so as to not be "on stage".
That's self-sabotage. I would be a hundred times more worried about anything deliberately self-destructive than I would be about mere laziness.

I got an email about this contest
https://edfinity.com/competitions?c=100
I don't know anything about it, but it looks like a good, fun contest.

Ds asked me this just yesterday. I told him it would be the opposite of the opposite (of the number). He thought that was funny.
MATH IS LOUD! :)

(Additive) Abelian Group Axioms
https://proofwiki.org/wiki/Definition:Abelian_Group_Axioms
Subtraction is defined by
x-y:=x+(-y) for every x,y
And the axioms imply
-(-z)=z for every z
So it must be that
a-(-b)=a+(-(-b))=a+b for every a,b
"Subtracting the negative of a number is the same as adding that number."
Note that "negative numbers" (numbers x satisfying x<0) are not really relevant here because an Additive Abelian Group need not even be equipped with an inequality "<".
Instead, what is being used is the negative -b of a number b.

I think it's just one possible solution technique, and not essential for the topic. Sometimes the solution writer could be a different person to the question writer, and they might not have the same solution idea in mind. Also the solution writer might not have a precise idea of what the student is "supposed to know".
Anyway, it's worthwhile knowing polynomial long division, and if you google it you quickly see many links, and the able student can get it.
By the way, if you happen to be dividing polynomial p(x) by linear function x-a (here x is the variable, and a is the constant), then the remainder is simply p(a), i.e. plug in a for x in p(x) to get the remainder!

How many more years does he have?

So kids being kids apparently the best part about the ceremony was the Photo Bombing. I was like :confused1: . He said that everyone ran around and put up their country's sign in front of the other team right when a photo was being snapped. So a NZ flag with the Irish team. One of the NZ kids jumped into the Chinese team's photo. I can only imagine how hilarious this would be if all the teams were doing it. My guess was that it was all the little teams doing it to the big teams. Can't quite see a Chinese team member joining the NZ team photo. :001_rolleyes: Unfortunately, ds forgot to bring his camera to the ceremony, so hopefully we can grab some photos from the other kids. Apparently, the Hong Kong youth orchestra played 3 composed-just-for-the-IMO pieces. DS *loved* that.
Kids will be kids! :)

Wow, there's so much practice and training for math competitions these days. When I was a kid, being prepared was mostly just knowing the time and place, so you could show up and take it.

Not sure if these fit but here are some "list threads" I had bookmarked.

Thanks for the suggestions.

DS10 was on the AoPS website and noticed they had some Python programming classes. (He's taking AoPS math classes) I know nothing about Python. I have only done programming in school courses many years ago using mainly Pascal, so I don't know these newer programming languages from more recent decades. Also I hadn't really thought about programming as a homeschool topic, until DS10 mentioned this Python class. He wasn't asking to take these classes (or any class) specifically. It was more a conversation starter about how he could learn about this topic.
Anyway, I thought it was a topic you could start on by "just playing around with it", and I'd heard of Scratch scratch.mit.edu so he made an account and has been playing around with it. I haven't really looked at what he's done yet, as in are the programs he makes just lists of instructions, or are there loops and if-thens etc, but I like the idea of just learning the general principles of programming, rather than any specific language (especially since I have no idea what programming languages are even used these days).
So Scratch seems like a good starting point, right? But any suggestions for how to proceed with other ways to learn about computing, in a homeschool environment, for a very mathy kid, with mathy parents who understand general theoretical computing and programming principles, but lack modern practical computing knowledge?

No news here.

After some more thought we came to a conclusion that seems so obvious in hindsight. Instead of trying to work through the AoPS books (which was not working) DS10 should take the AoPS classes. It's more expensive, e.g. $300 class versus $50 book, but if it works I can live with the cost. Another concern I had had about the classes (versus the books) was that once enrolled in the class, you are committed to the pace and schedule (and lose the flexibilty to speed up, slow down, take a break) but I think this commitment can turn into a positive. DS10 understands what would be required, and is on board with this. He took an AoPS class for AMC 8 prep and really liked it, so he knows the format and enjoys it.
So I feel good about this choice for Math for DS10. (But for the rest of the subjects and the rest of our children our homeschooling plan is still a shambles. :crying: )
Update: DS10 has now started to take a couple of classes, and it's working out really well. He really just needed that extra structure to stay on task (and he finds the live classes fun). So we may keep doing the classes in the future. Or we may figure out how to provide the structure at home (which, as parents, we had previously failed to do).

I assume the results will be given at the end of the round 1 time window. I believe this competition is new, so we can't look back at any "what they usually do".
