Table Trash-This has helped me so much this year. Each of my tables have a small trash can. If we are working on something super messy, I place these on the tables so that students can place their trash in the can. This way my students are not getting up during the lesson. I also assign each of my tables a table captain each day. The "table captain" is in charge of dumping the table trash, gathering materials for the table, wiping the table, passing out papers to the table, and stacking chairs at the end of the day.
