Math grades are taken generally from 3 sources: homework, tests, and in-class assignments. A big chunk of "in-class" work that is scored are the students' daily Math Boxes which contain an assortment of review work which can be done using any resources available in the classroom. Remember that the first place students should look to for help in math (including HW) is their Student Reference Book, or SRB. I generally will collect 2-3 Math Boxes per unit equaling 20-30 points.
