Research shows that students learn best when they can see worked out solutions for about half of their math problems. As teachers, our primary interest is in helping students learn. Our math tutors are available to help you on evens.
The Classwork problems are intended for use in class so we do not show solutions for them. The CPM teacher manual advocates only assigning the Homework problems for homework.
We skip chapter test problems, writing problems, group problems, or problems not generally assigned for homework. If you believe we have skipped a solution that should be there, please use Feedback in the bottom-of-page menu.
