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

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.
