I give my students an opportunity to show their great grades in the classroom. At the beginning of the year, I give them a different color construction paper to use as their link color. For every test or project grade that reflects A work, both in my classroom and in their other classes, the students cut a strip of their color paper, write the subject and the grade on it, and staple it to the previous link. Along with the link added to the Chain of Great Grades, the students are entitled to select a reward from the reward jar. As the year goes on, the chain becomes longer. I love to look up and see our great grades hanging around.
