I recently posted pictures of the tubs my children decorated to hold their school work, and I thought I'd show you here how I have organized our homeschool this year.
Each child has his or her own tub that holds all the books they need each day. That way, there will (hopefully) be no more, "I can't find my math book!" scenarios
All of the tubs are kept together in one location with the teacher's guides, resource books, and any other supplies that might be needed.
That bookshelf is in what was formerly the breakfast room, which might make a perfectly adequate and darling little area for an average size family, but which was overwhelmed by our numbers. I pushed the little breakfast table which once held our little family over against the left wall so there is room for more children to sit and work. The schedule and a map of the world are also posted on that wall.
That's what is working for me!
