how to: consumable workbook into re-usable

I have a pile of consumable workbooks that have been gifted to me over the years.  Some of them are nice enough that I have been trying to think of a quick way to stretch their usability just a bit.  Last week I came up with the solution!  I removed the staples, cut down the middle of the workbook, and put most of the pages in the front pocket of a folder.  The front and back cover, along with the title page, table of contents and a page protector sheet, were 3-hole punched and put in the middle thingy.  Yes, that is the correct terminology.  Lovely word, that "thingy." 

The page P is currently working on goes in the page protector, and the rest are clipped to the front of the folder to cut down on floppage.  Again, I use only the most accurate terminology.  This particular workbook came with stickers and a "money bag" to track progress through the "levels."  There happened to be extra space on the page the stickers were on, so I drew more coin stickers with permanent marker to be cut out and used with subsequent kids.

 I think this will work well.  It doesn't take up much space, is easily disassembled when I'm done with the unit.  Hooray for quick, free solutions to minor problems.
