Generally, I have the students grade their own homework each day. This gives them immediate feedback and forces them to read their own handwriting! (which seems to be a growing problem each year.) Homework is a completion grade of 10 points. I do periodically take grades on homework, if we have worked on a certain skill for two days and they have completed homework on the skill both nights. Quizzes are weighted, being valued at 30-50 points, tests are worth 100 points. The only down side to this is that some students loose motivation to do their best when it is only for a completion grade. I try to motivate them by challenging them to raise the number of students in class who completed the homework correctly (100% correct) five days in a row. That means if 6 students complete the homework with no errors, the next day the number of students must exceed 6 students...and the following day the number must exceed the day before, etc. If this happens, I allow the students to bring a snack and eat it in class. It does motivate them!
