And all the kids LOVE to draw on their boards. And I can take a picture of their masterpieces when they're done, instead of having a stack of papers to keep up with (because no way can I ever throw away one of their precious works of art!)
My husband found some great dry erase markers at Wal-mart - they're called Expo "Click" and I love them because there's no tops to keep up with. And they write really well.
At this time of year, when we're all pining for a Spring Break, we'll take anything we can get to make school more interesting. And hey, we're saving trees, too. Go us!
