I teach an American elementary school curriculum at my school. We mainly use American textbooks and workbooks. I don't get to teach all the subjects at one time, but the students (depending on their grade level) get the same core classes an American student would get: reading, science (it's actually called non-fiction), grammar, phonics, writing, speaking, social studies, and even math.
My favorite class is science! (Then math.) I love all the fun experiments there are in our science book. Today, my kindergarten students learned about shadows. We had a blast!
