I use the Mountain Math program and I keep all of the pieces in the pocket charts I use on my bulletin board. I used two full size basic pocket charts. It is very easy to then rotate front to back or back to front. Did your kit come with pictures of how to set it up with pocket charts? If not you may be able to find some on their website. I purchased some very inexpensive basic pocket charts from WalMart and I use some push pins to help hold up the extra heavy pockets. In math there are a few pieces that don't fit well in a pocket chart pocket by itself, so I have page protectors cut to fit those pieces and then I place those into a pocket.
I hope this helps. I'd love to hear how you like the Mountain Language program after you have used it for awhile.
