These reminder slips are great for encouraging student organization and responsibility.
In preparation for the school year, I print and cut them out in June or September. Then I put them in separate envelopes to be used throughout the year.
Students know to keep the slips until they have completed the task and then they return them to a TASK COMPLETED box. Students put a giant red check mark on the slip before putting it in the box.
I've never opened the box and counted the slips for each student, but that might help when it comes to gathering data for report cards.
