Ours were thematically grouped, usually by phoneme. For example, I remember that one week in elementary was /hw/ ("what","when","whichever"). I never had to study for spelling, probably because reading was my favorite thing to do. Well, until I had one teacher who tested that we'd memorized the list of words... Explicitly studying spelling ended after 5th grade (rural elementary school in Texas, late 80s/early 90s) Spellcheck is a wonderful tool, but relying on it can lead to embarrassing results. I would not want the kids in my life using it until they have their own grasp of spelling.
