I taught a self contained PS 7th grade class in CA about 10 yrs ago. The subjects were world history from around 500 to 1600 or so... Language arts, pre-algebra (or more accurately pre-pre algebra, though the kids weren't tracked so there was a wide variation in skills), life science, PE, computers/ health (1 sem each). 8th grade got us history instead of world and earth science instead of life and music/art instead of computers/health.
