I love Post-it notes for scheduling my homeschool day!
Since they can easily be removed and re-stuck, I can rearrange and modify my schedule without erasing or starting over as I would have to in a planner.
Because they are bright and good sized, we can all see what we need to be doing at once.
I use 2 poster boards and mark the time on the left side in 30 minute increments. At the top, I put every person's name on a different color Post-it note.
This system makes it a breeze to schedule my day
