Suzukimom, it sounds like you have a good plan. One thing that is working well for us is that I just planned time for each of 1. morning basket (together), 2. reading/narrating, 3. writing/Spanish, 4. math, 5. listening/narrating (ie. Mom reads aloud), and 6. “riches”(together). I had originally tried to schedule different amounts of time for each child, based on age/ability, but this week we started just doing 20 minute blocks for everyone, so everyone switches activities at the same time.
The specific assignments change for each student (eg. “writing” varies from letter formation and then some colouring time for DD5 to dictation and written narration for DD9) Once everyone has spent 20 minutes on each subject (30 for math), then we are done for the day. I figure that’s a well rounded day, so I’m content with it. We just rotate through assignments/readings within each subject area, so eventually we get to everything, which is basically your module idea.
You would of course adjust the ‘subjects’ for your kids.
