Does anyone have ideas for marking desks on the floor? My students are constantly moving the desks forward and around...not on purpose, but it just ends up happening. I moved my desks into groups and the desk arrangement is perfect! Everyone is at an angle so very few kids are completely facing away from me. I used painter's tape to mark the area around the groups and it worked well this week, but it is peeling away when the kids walk on it and move the chairs, etc. Does anyone have any durable suggestions for marking desks on tile? It is nice being able to prevent the desks from migrating too close to the front of the room and being able to ask kids to just fix their desk. Thanks!
