Note to teachers: The new Algebra that we are building will be topic driven and will not be listed according to course. I think this is going to make it easier for students to find what they need. Since you may have lesson plans set up with this old navigation, I'll leave them up for you. But, we won't be doing any maintenance on them, updating broken links or adding new things in. Please just bookmark this main chapter page to be able to find them after we are done! Go to the main Algebra navigation page to access the upgraded lessons
