Thinking outloud here… I wonder if it would work to make a planner for each subject. For example, you schedule the ancient books out for the year, divided into terms/weeks/etc (could do it for all ages, or by younger, middle, high school). Then you do the same for each science. Math. Everything. When you have a child in ancients using physical science in MUS Gamma you pull out those schedules for them. Yes, the have to look at 3 different schedules, but the entire year is planned out for each child after. Alternately, you could have them look at each schedule at the beginning of the week and they could write it out into one schedule, all the subjects on one page. You give them the Master Schedule for that resource/course of study, and they copy it into the weekly schedule they will use. Sometimes they might be on Week 16 for history and Week 13 for science, but things are checked off the Master Schedule as they go so you always know where they are and where they’re going.
Great minds think alike! I realized that I have done this for years with my 12 week charts. It’s easy to cut and paste a subject into another 12 week chart. I went around the world to end up at my own front door.
Someone on the AO forum linked to this planner a few days ago and I’ve just downloaded it and input our whole year. Then I remembered this thread and came to post, and here you are discussing planning again. Anyway, this might be helpful. it’s a spreadsheet, in which you can input the entire year for each subject, and then it will generate printable weekly schedules from that information. You could then copy and paste a subject into a new copy of the spreadsheet when you are ready to reuse that plan.
It’s a free download, and then she asks you to come back and make a small donation if you like it. I will be donating more than just the two dollars she suggests. This is exactly what I needed.
