This rubric was designed to asses students after they create a math game about addition and subtraction. This assignment may be suitable after a class took a test in order to display their understandings in a form other than a test since some students are not the best test takers. It is a way for them to show that hey understand the material. The games can also be played as a stress reliever after the test. This project can also replace a test if the teacher chooses to do so.
