Sometimes it's a struggle getting students to complete and turn in their homework on time. If you are having issues with that in your classroom, this is a great incentive for you to use! It is quick, easy, and fun for the students! When they turn in an assignment, they write their initials in one of the boxes on the grid. At the end of the week, you play bingo and call out random squares. If students have their initials in those boxes that are called, they win a prize!
