A great tool for those students who constantly ask "Am I done yet?".
Cut out the numbers and laminate them as well as the blank board. Use velcro to put the numbers on the board in reverse order (15-14-13, etc). Students can then pull a number every time they finish a task. You can start with 5, 10, or 15 items. When they pull off the number 1, it will say "all done" and they will know they completed their work.
