One classroom management strategy that I found to work great is having a table monitor to distribute and clean up table materials and text books. It makes transitions much smoother and the kids love the responsibility. Each Monday they rotate so each child gets to be table monitor several times throughout the year. I have used SO many different signs including magnets, frames, and stickers but nothing lasted. I finally found these cheap and durable frames from Ikea and made little signs to slip into the frames. They are double sided and did I say durable?? They do not break no matter how much the kids mess with them and they wipe clean! Win- win!
