Also, I'm interested in specific country-by-country information. In particular, one question interests me, which is that in Britain, young children tend to be taught by a single teacher each year, who is expected to teach all the required subjects, including Maths, Science and English. Is that the case where you are, or did you have subject specialists at your age?

That is similar to how it is done in most primary schools in Germany (at least when I was there). We had one teacher for everything except stuff that one person can't teach - so swimming (graded as a subset of sport/P.E.) was taught by two different teachers (since you always have to have two teachers during swimming). The turkish children also had a teacher for turkish, and that was the only male teacher in the school.
Other than that, everything was taught by the same teacher.
Well, I don't have many memories of learning math for myself, so here is the one that I have: I learned the "Einmal Eins" during long car rides, during which my mother would quiz me. The Einmal Eins is essentially just all multiplications from 1*1 till 10*10. Problem is, you kinda are expected to not just do them in your head, you're supposed to know them by hard. So that's why I did that.
Other than that, I can only tell stories about the kids I teach (as a private tutor).
One girl I had learned fractions for the first time, and it blew her mind. I eventually explained it with imaginary pieces of cake. I get the feeling that talking about cake helps her with pretty much any topic.
As to specific teachers and things they did wrong: oh, boy.
My math teacher from 5-7th grade was awful. She only taught through extreme repetition with the help of boatloads of worksheets. In the end, it stopped us from doing any of them - you got a bad grade if you even forgot ONE, so why even bother?
After that was done, I was put in the advanced math course (advanced courses in the schoolform I was in are needed to get any further than 10th grade, but german schoolforms are complicated) and had the hardest math teacher in school. Hard, but... actually, not fair at all. He essentially takes the best five people in the class and ignores everyone else. Luckily, I was one of those five, so I had a blast. We blazed through topics at about double the rate the other advanced course did. It was awesome. And he was a dick, in all regards. A very uncomfortable man - but I always felt that a bit of praise from him was worth more than the best grade.
When I started my "Abitur" (11-13th grade), I had a teacher that just didn't give a shit. He only taught those that really, really wanted to AND was talented in it (which was exactly one person), everyone else just got a barely passing grade. I was grateful for that, because mathematics at that point become very... abstract.
As a tutor (and mostly math at that), I have to fix the mistakes of teachers all the time. Teachers who treat their students like university students, expecting them to understand abstract concepts and connect them without help and without introducing them to the methods needed.
But probably the worst one pertains to the "cake" story I had above, and it shows something that is (in my humble opinion) one of the biggest problems in teaching: they act like everything they say, even the extreme oversimplifications are true. In this case, my student was taught that THERE ARE ONLY NATURAL NUMBERS. When she asked if you could divide five by three, she was told it was impossible.
Look, lady, just because they aren't ready to learn about it, reinforcing the idea that everything they can't do yet is impossible isn't the best way to go.
So you come to a point where students have problems understanding new concepts because those very concepts were impossible just last lesson. Those teacher set up rules (with good intent, sure) and them break them. She needed a lot of time to understand that yes, you can have numbers between one and two.
This is also a problem in chemistry, where students essentially walk in the footsteps of science - they start with really old (and thus, simplified) models of atoms and reactions and then essentially follow history with ever more complex versions of the systems they already learned. Problem is, the teacher treats the version they are at as if it is the absolute truth. Students then get taught a new one that pretty much invalidates the previous one, often without explanation as to how we got to that conclusion, because a lot of chemistry teachers don't care about the history of chemistry or teaching the scientific method.
