Really cute pages to be used as whiteboards. I have one of these for each of my students and one for myself as well. I recommend printing each side on its own piece of card stock. When you have them printed you may want to trim the left side edge to match the right. I trimmed mine leaving 1/8 of and inch on the right to match the left. Once they are trimmed you need to laminate them (both pages back to back) so that you end up with a two sided whiteboard. The center of the blue side is balnk and the center of the green side has a graph paper grid that is light enough to write over but still dark enough to use for graphing. I keep a set of four at each table group.
You could also put them back to back in a sheet protector and use packing tape to seal the top if you do not want to laminate them!
Thanks and Enjoy!
