Common Core Algebra 1

These interactive lessons use dynamic graphing and guided discovery to strengthen and connect symbolic and visual reasoning. They give the student a hands-on visual exposition of all Common Core Algebra 1 topics, reinforced by adaptive exercises and randomly generated tests. All exercises and tests are checked and graded automatically. Hover the mouse over a link below to see an example from that lesson, or click on a test link to see a concise summary of a group of lessons. Relevant standards are listed after each lesson’s exercises, with a ' (prime) denoting a distinct link. We also provide a course glossary.

The Common Core and other standards cover many algebraic topics before the first actual High School Algebra course. Therefore, students may have already completed many of the lessons and exercises below in an earlier grade, or in a summer preparatory course. If so, those assignments will be treated as already completed in this course also.

Students should have scratch paper available, access to (software or hardware) numeric calculators except during the Arithmetic Review chapter, and other students or a teacher to ask for help when they are stuck. All students are encouraged to both give and receive mathematical explanations with their peers. Please send us your comments, questions and suggestions. (Lessons without links yet are under development.)
