I've decided to go back to using a large master schedule to allow me to see at a glance what each of my 8 children should be doing at any time during the day.
I used 2 poster boards and marked everyone's name at the top. Then I marked off 30 minute time slots along the side. I filled in the subjects we all do together and then let everyone choose a different color Post It note pad.
The oldest kids were allowed to arrange their own Post Its, as long as it didn't interfere with the subjects I had already arranged.
Then, using a cork board, clothes pins, ribbons, index cards, and push pins, I created a visible reminder of how each child is progressing on his or her daily schedule. I hung ribbons and clipped index cards with subjects written on them under each child's name. I put the subjects that should be done before noon on the left side of the clothes pin, and the subjects done after noon on the right so I could easily see if everyone is using their time wisely.
As each person finishes a subject, he or she flips that card over.
At a glance, I can tell which subjects have been completed by which children. I can see that in the above example Cami has completed her chores and her S.O.A.P. journal, and should be doing spelling next.
Hopefully, our master homeschool schedule and assignment cards will keep everyone, including mom, on track. (This photo shows the schedule in its unfinished state.)
