Math textbooks usually include answers for odd problems, so I assign both odd and even problems. To check the work, I grade on a scale of fifteen points and pre-select five even problems to check for accuracy. I subtract one point for incorrect problems out of the fifteen points. This way, I'm not grading endless amounts of work and I assess my students' needs in that area. If students turn in answers only, they get graded from five out of fifteen points. Incomplete work gets graded starting from eight out of fifteen. This encourages students to finish their work. The lowest score they can receive on complete homework is ten out of fifteen points, which is better than a zero.
