I found this piece of genius on Pinterest. It can be used for a TON of different activities including turn taking, instruction giving, random selection of instructions, etc. The possibilities are endless.
The link for the directions I followed is below, but the short version is this: I got a lazy susan (for FREE by just asking on Facebook!). I unscrewed the bottom piece off of the top and painted the underside of both pieces with chalkboard spray paint. I then re-attached the bottom piece and added a large red felt arrow over the screw hole. I used a small hinge and a piece of scrap board to create a support.
VOILA! Story Time MAGIC.
