If you want the convenience of a lap-size whiteboard, you can slide a plain piece of cardstock into a page protector and use dry-erase markers on it. Of course we use dry-erase markers on page protectors all the time, but it only just occurred to me that I could use the same idea for a small, portable white board. Before sliding it into the page protector, I drew lines on one side of the cardstock. The other side I just left blank. Snap and I have been using this every day with Primary Arts of Language, and I keep it right in our P.A.L. basket. Handy, quick, cheap cheap cheap.
