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 8th Grade Math (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 12-month online 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 8th Grade Math (Prealgebra) appropriate for my accelerated student?

For advanced students, you may be interested in 8th Grade Math Honors.

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

Does Thinkwell's 8th Grade Math (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. View the content, standards, and objectives for our 8th Grade Math/Prealgebra course HERE . Websites such as www.achieve.org can help you determine your state's standards.

What if my student needs access to the course for more than 12 months?

You can extend your subscription 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 8th Grade Math (Prealgebra)?

The pace of your course is up to you, but most students will schedule one school year.

Can I see my grade?

Can my student use a calculator for Thinkwell's Prealgebra course?

The Prealgebra curriculum is designed to support critical thinking and problem-solving using a variety of tools, including calculators when appropriate. While some questions may specifically suggest completing the problem with a calculator (and will include instructions to that effect), students are generally encouraged to choose the method that works best for them. A calculator can be a helpful tool for checking work, performing complex calculations, or visualizing mathematical relationships. See our Calculator Policy.

Can I get a transcript?

Yes, there's a final grade report print option in the My Grades section. Contact techsupport@thinkwell.com 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 techsupport@thinkwell.com 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 the exercises multiple choice?

The online exercises and course assessments are primarily multiple choice, and they are graded automatically with correct answer solutions. If you prefer open-ended questions, we recommend using the printed versions of the assessments in our companion books, which are primarily free response.

Is Thinkwell's Prealgebra spiral or mastery-based?

Thinkwell math courses are mastery-based, ensuring students thoroughly grasp each concept before progressing to the next. While mastery is the primary goal, our courses integrate regular review opportunities strategically throughout the course material. These reviews reinforce previously learned material, solidifying understanding and identifying areas for improvement. By combining mastery-focused instruction with ongoing review, Thinkwell Math equips students with a strong foundation in mathematics, setting them up for long-term success in the subject.

What is Thinkwell's Refund Policy?

We offer a full refund of 12-month subscription purchases within 14 days of purchase, no questions asked. However, refunds are not provided for completed courses. No grade reports, certificates, or transcripts are provided for refunded courses. For Essential Review courses, the refund period is 14 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 techsupport@thinkwell.com and we can provide them access to a demo site.

How long does it take for my optional printed course materials to arrive after I've ordered them?

Orders for the optional printed books are processed within 1-3 business days (workdays excluding weekends and federal holidays) and shipped via UPS Mail Innovations® Expedited mail service. Shipping may take 12-14 business days, or longer pending delays. We're unable to send tracking information automatically, but you may request a tracking number after the order has been processed (1-3 business days).

Do I get credits 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 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. Learn more about our accreditation HERE.

Is Thinkwell math conceptual or procedural?

Thinkwell’s approach to teaching and learning mathematics blends conceptual understanding with procedural fluency. Overall, we aim to strike a balance between concepts and procedures in our content which allows students to develop the skills and knowledge needed for success in mathematics. We recognize the importance of building a strong conceptual foundation when learning math. Prof. Burger emphasizes the "why" behind mathematical principles in the video lectures so that our students can develop a comprehensive understanding of the ideas underpinning the subject. We also believe in the benefits of procedural fluency, recognizing that mathematical proficiency requires not only understanding but also the ability to apply procedures accurately and efficiently. Through systematic practice, students master various mathematical techniques, ensuring they can solve problems confidently and accurately.
