Having a class set of dry erase boards is a great way to save paper and / or have all students participate in a group lesson by writing their response.
But, dry erase boards are pricey.
Plastic sheet protectors are a great alternative. I especially like being able to slide in a worksheet or graphic organizer as an environmentally-friendly option.
However, those are too floppy to have kids write on and hold up for you to see at a glance. So I present a wonderful (read: cheap) alternative...
You can even pick a color to match your classroom.
Because things like that are important. ;)
