Our current 7th grader's schedule looks like this (times given are approximate):
Personal bible study and scripture memorization daily. My husband is in charge of this one, but I believe he requires two verses memorized daily from the Book of James, and 2-3 Lessons completed a week in Studying God's Word.
History daily - one or two days per week Canadian History, Bible history/Ancient three to four days per week. 30-45 minutes.
Science - 5 days per week. Apologia General Science (3 days); read through Secrets of the Universe the other two days. 45 minutes - 1 hour for Apologia, less for the other books.
Language Arts - Spelling Wisdom 3 times/week (as long as it takes - 15 minutes maybe?), Ancient History based Writing Lessons (includes vocabulary) twice a week (30 minutes); poetry twice a week - we just read the poems at this point. We have finished JAG and are taking a break from grammar until next year.
Math - 5 days/week, 4 days MathUSee pre-algebra, one day Focus on Problem Solving. Usually one practice page or test per day.
Literature - reading 5 days a week. 20 minutes or so.
Art/Music - picture study once a week, drawing and/or painting at least once a week (these are done more as free time projects for him); composer study is casual - we listen to or play classical music/hymns regularly as a way of life. Violin/piano practice daily. This can go on for hours.
Foreign language - Latin daily, french two or three times/week half an hour, but should be more.
Typing - daily 10 minutes
Logic - twice a week formally, but trying to encourage logical thinking more often :)
Personal development book weekly - 1 chapter
Computer skills - learning to use Microsoft word a few times per week. We bought the Alpha Omega lifepacs for him - he likes them; I think they're a bore.
Geography - daily computer "game" 10 minutes. Weekly study of Africa with David Livingstone - 30 minutes
That's all I can think of at the moment.
