I found these plastic placemats in the clearance aisle at Wal Mart several years ago. It was after summer and these little mats were leftover from the big display of things to use at a picnic. I snatched them up for something like 20 cents a piece. They became my "hot spots" for the classroom floor. They're double-sided with different prints on each side and they are easy to move when needed. Since they're so thin, they store very easily. If one ever gets torn or marked on, no big deal! They were super cheap!
I use these "hot spots" for a variety of different things. They might serve as the center of a circle (easy for kids to see and walk around), they might be the place where you stand when you're going to toss a beanbag, they might be the special spot where you stop for a cakewalk type game or "London Bridge" type game. They can even be obstacles if you say something like "add a locomotor movement that matches the music BUT don't step on the hot spots!" In a pinch, they could be used for a time out spot. They really can be used for anything... here's an example.
The hot spots were an easy way for me to create some boundaries or focal points for the room. I've had them for three years now and they're still in great condition!
