Get a dishcloth (not too thick) and make it a little damp and stick it under your surface. That will stop it moving.
I have one of the tupperware mats. I don't often use it, at least in part because I don't have any where large enough to put it out. When I have used it, it's quite good, it makes it easy to see how much more rolling you need to do, and you can also lift it up, turn it over and then peel the pastry off it onto your cooking item:-)
