We used 3 ring binders this year for each child. By late in the year some of the children needed a second binder. It worked well, they simply had dividers. In other years we saved papers in a hanging file folder and at the end of the year we used our ProClick to bind them.
Next year we’re playing around with the idea of using composition books for most things. We’ll have some geography pages I’ll be printing all year that I may print up ahead and bind with my ProClick for each child into a spiral bound notebook. I’ll make that decision before fall. We may go with one of the other 2 options again.
