Some of my favorite workbooks can be so expensive to purchase 8 times (or more!) so I have found that an inexpensive option is making them re-usable by laminating them.
I am placing each dismantled sheet in a letter-sized laminating pouch and feeding it to my inexpensive duck laminator (that I purchased from Walmart) and storing them in my file cabinet in a large labeled folder for each dismantled workbook. I found it easy to keep like pages together by running a sharpie around the outside edge of the laminated card to tint it a bit. That way red cards go back with the red cards. When I get really good, I will color coordinate the folder to match the cards. I am just not THAT good…yet 😉
I place a few of these double-sided laminated cards out on the school shelves (separated by subject) in a magazine holder for use and replace when needed. I am still deciding what kind of marker to use for this…right now it is a marker that I keep in a little holder attached to the magazine holder and a colorful rag to wipe it off with that is pinked from a beautiful piece of remnant fabric.
This does save me a ton of visual space on the school shelves, looks neat, and you can find what you need at a glance. …that, and if my soon to be highly mobile toddler knocks it off the shelf, it is somewhat durable and I don’t have that much to pick up! 😉
