This is a excel spreadsheet that you can place on the top of each desk however you choose. You can edit the information on it to ensure that what is on the placemat is what you are covering in your classes. That way the students when looking around the room can constantly have it reinforced to them that this is the information they need to know. It can be a great resource to them. It can be laminated as well so that students can write on it in class with dry erase makers if needed.
