This page will help with students turning in work. It will remind them of the important things that should be on their papers every time. Copy it on cardstock, attach to construction paper, and laminate. Students put their papers underneath the sign, so there's no peeking at classmates' answers!
In addition to this page, have clothespins clipped to your turn-in tray (with their name or number on one side, and their name or number and the word DONE on the other), and they turn theirs around when they've turned their work in. Saves you from having to go through all the papers to figure out who didn't turn it in yet!
