Sometimes things get too hectic to recognize individual achievements, so I started a 'Superstar' bulletin board. When any of my students makes 100 on a test or special project, it gets put up on the board. I also have an achievement chart with each of their names where they can place stickers for each 100 put on the board. When they get five stickers on the chart, they can choose a prize from the prize box. The bulletin has become important to the students, not only for the prizes, but for the visual and classroom recognition. They can keep track of their progress themselves and know what it takes to get to the next prize slot. Whatever their goal, it has made them try a little harder on their work.
