Instead of regular file-folders, I used folder-pouches that had velcro-closures, and cut them open. I used 3 folders, and cut the closure-flap off 2 of them. There are 2 folders displayed in the picture; the third folder is glued on the back, joining the two folders together. Here's a close-up of the left side:
I adhered peel and stick magnet strips (spent $3 at stuff-mart) to the folder for the tiles to stick to. Here's a close-up of the right side:
Lay it flat on a table to work, and simply fold it up for easy storage when you are done:
I was concerned about how thick it might be with all of the magnet strips and tiles in there, but it's barely thicker than my hand:
It fits easily into my kids' workboxes:
Or into my Teacher File Box:
Or the rubbermade tote I use to hold our other AAS supplies:
I've opened and closed it several times to see how the tiles hold up. They rarely fall off. The first three pages always stay intact; the last page I open does sometimes drop a tile or two as I open it, I think because it's not a reinforced page. I'll probably try gluing another folder to the outside to add stability.
This would also work great for people who want to take AAS or the new All About Reading on the go--pack up the tiles too! Enjoy!
After using this for about a year, here's an update.
