What Parents Are Saying. . .
"We have used Thinkwell for two school years now, 7th and 8th Math, as well as Geometry and Algebra 2. It is the favorite math program with both my son and daughter. They enjoy the teacher and his presentations, and feel they are very clear and complete. For us, Thinkwell has been a blessing, and we intend to continue to use it for the rest of our math needs. We have also shared this news with our friends, and several have also been won over to the Thinkwell side!”
– Delana J.
"We've used Thinkwell for 6th and 8th grade math. In the past we have used Saxon, Teaching Textbooks. Out of all the products Thinkwell is our favorite. Our boys really responded to the instructor. They thought he was funny and that he showed them methods and ways of doing things the other programs left out. Their test scores improved dramatically. We felt it was much more comprehensive than Teaching Textbooks even a year ahead and way more engaging than Saxon. We will definitely be using it again next year. As a mom with five kids I really like how it took a load off of me. All around super happy with this product! We have shared with lots of friends.”
– Bethany B.
"We love Thinkwell. If we could take all our classes from them, we would. My kids talk about the pre-recorded lectures as "My professor said" and "my professor does" just as though they had real face-to-face contact with the instructor every day. We can't wait for next year. We're already planning to take two math and one science class through Thinkwell next year. I tell everyone about Thinkwell!”
– Lessa S.

Frequently Asked Questions About Thinkwell's Prealgebra

How do Thinkwell courses work?

Your student watches a 5-10 minute online video lesson and then completes the automatically graded exercises for the topic, receiving instant correct-answer feedback, then moves on to the next lesson! The courses are self-paced, or you can use the daily lesson plans. Just like a textbook, you can choose where to start and end, or follow the standard table of contents.

When does my subscription start?

It starts when you're ready. You can have instant access to your online subscription when you purchase online, or you can purchase now and start later.

What math courses should a student take?

A typical sequence of secondary math courses completed by a college-bound student is: Grade 6 Math > Grade 7 Math > Grade 8 Math > Algebra 1 > Geometry > Algebra 2 > Precalculus. For students looking to include Calculus as part of their high school curriculum and are able to complete Grade 7 Math in 6th grade, the sequence can be: Grade 7 Math > Prealgebra > Algebra 1 > Geometry > Algebra 2 > Precalculus > Calculus.

Is Thinkwell's Prealgebra appropriate for my accelerated student?

For advanced students, you may be interested in our Honors Prealgebra course.

Does my student get school credit for Thinkwell's Prealgebra?

No, only schools are accredited and Thinkwell is not a school, though many accredited schools use Thinkwell.

Does Thinkwell's Prealgebra meet state standards?

Some states set standards for what topics should be taught in a particular course. Thinkwell does not have a course version for each state. Instead, the course is built to national standards to be inclusive of all states. Websites such as can help you determine your state's standards.

What if my student needs access to the course for more than 3 months?

You can purchase extra time for $19.95/month.

Can I share access with more than one student?

The courses are designed and licensed to accommodate one student per username and password; additional students need to purchase online access. This allows parents to keep track of each student's progress and grades.

How long does it take to complete Thinkwell's Summer Edition of Prealgebra?

The pace of your course is up to you. We've broken down the full course into 8-week segments. Do as little or as much as you like in a week. If you're pressed for time, we recommend taking the Chapter Pre-Test first to identify the topics you can skip, and those your student might need to study. See the Pre-Test Guide for the list of topics that correspond to the questions on the Pre-Test.

Can I see my grade?

Thinkwell's course software tracks everything your student does. When logged in, your student can click "My Grades" to see their progress.

How are grades calculated?

The course grade is based on the scores for the Chapter Tests, Midterm and Final Exams.

What is acceptable performance on the exams?

As a homeschool parent, you decide the level of performance you want your student to achieve; the course does not limit access to topics based on performance on prior topics.

Can I get a transcript?

Yes, there's a final grade report print option in the My Grades section. Contact with any questions.

What if I change my mind and want to do a different math course, can I change?

If you discover that you should be in a different course, contact within one week of purchase and we will move you to the appropriate course.

Can I print the exercises?

Yes, but completing the exercises online provides immediate correct answer feedback and automatic scoring, so we recommend answering the exercises online.

Are exercises multiple choice?

Most of the exercises are multiple choice and they are graded automatically with correct answer solutions.

Is Thinkwell's 8th Grade Math (Prealgebra) built on "continuous review?"

Thinkwell's 8th-Grade Math (Prealgebra) is carefully constructed to build on previous knowledge, reinforcing key concepts every step of the way. It is not only a reflection of empirically effective instruction, but also reflects Dr Burger’s philosophies learned over a career of teaching mathematics, emphasizing a solid foundation that addresses why students need to learn certain concepts. Finally, Thinkwell's 8th Grade Math (Prealgebra) is intentionally designed to work for a wide variety of learning styles.

What is Thinkwell's Refund Policy?

We offer a full refund of 12-month subscription purchases within 14 days of purchase, no questions asked. For Essential Review courses, the refund period is 3 days. Optional printed materials are printed on demand and the sales are final.

How does my school review this course?

Should your school need to review a Thinkwell course for any reason, have the school contact and we can provide them access to a demo site.

Do I get credit for a Thinkwell course?

Generally, only schools can award credits, and Thinkwell is not a school. We can provide you with a certificate of completion and a grade report. However, if you’re pursuing credit with a particular school or institution, it might be helpful to know that the full versions of the Thinkwell math courses are accredited by the Western Association of Schools and Colleges (WASC) as a Supplementary Education Program. For California students, Thinkwell is also an approved A-G online publisher. See the Accreditation Page in the menu below for more information.
