I don't know if it's too much offtopic, because it's about elementary school, but hey, let's go: I went to first 2 classes of a private school in Sao Paulo in '89-'90. I was a smart kid and had 9.5-10.0 average (0-10.0 scale) despite I had to learn the language at first. One day in class, the teacher of biology (or sth like that) started talking about fish and stated that a dolphin is a fish. I argued with her saying it's a mammal, she said I was wrong, I didn't give up, but for the moment it was case closed. After a few days on the next lesson with her, she raised the topic once again to say that I was partly correct, because a dolphin is a "mammal-fish". We've had a laugh with my parents to this day, and I was always wondering how high school and college education works around there if a science teacher in elementary school can be so dumb. Our education system in Poland is far from perfect, not to say completely broken, but I must say that at least teachers in elementary have the basic knowledge not to miseducate kids.
