I am doing my practicum and have run into a bit of a problem. When I got to the school (high school math and science) the main teacher told me they didn't have textbooks. When I asked what I was supposed to teach, he said that he had all grade levels so there wasn't a curriculum, but the kids functioned at third-fifth grade with a few above and a few below. So, should I be teaching at the third-fifth grade level because that is where they are, or should I try to teach them high school science type things like atoms and rocks? Should I meet them half between and teach middle school-like science? Ideas are more than welcome!
