Below is an image of the progress posters I have at the front of my room. When a student successfully completes one of the exercises, they are allowed to stamp that exercise as proficient. Students cannot wait to put up their stamp. If they completed something at home, they are at my door first thing before school to stamp it.
At the end of each week, I give students a raffle ticket for each stamp for that week. I then draw for prizes at the end of the class. Students love this and get all excited. It's a nice way to end the week's work on a positive note.
