Here's a small teaching tidbit of the day! If you have your students use dry erase board throughout the day, here is a simple solution passing out tissues to erase the boards. Purchase an inexpensive packet of socks at a store. These socks make perfect dry erase board erasers. They are cheap, easy, and can very easily be washed!
You can also create your own dry erase boards. Go to your local home improvement store (Home Depot, Lowe's, etc.). Ask them for a piece of melamine. This piece typically comes in a 4 ft. x 8 ft. rectangle. Double check the surface of the melamine. You want a surface that is smooth, like plexi-glass. It could also be a material called lexan. The home improvement store will cut the board for you into smaller pieces (I would recommend 1 ft. by 1 ft. squares, which will give you 32 dry erase boards.) It is definitely cheaper than purchasing a set of dry erase boards. They work perfectly as dry erase boards. Go for it today!
