What Parents Are Saying...
"I love Thinkwell math! My son and I think Professor Burger is awesome. We tried a few different math programs but nothing compares to Thinkwell. The concepts are presented in a way that makes them so much easier to understand. I go through the lectures and problems with my son most of the time and I am finally learning Geometry (my nemesis in high school and college). Professor Burger uses humor which makes it even better. We will definitely continue to use Thinkwell. I am so grateful to have found it!"
– Tina C
"We are using Thinkwell's Geometry, and we love it. The lectures are fun and well organized. The notes for each lesson are easy to follow and provide all the info needed to complete the problems. My son is excelling with this program, and I find it very easy to jump in and help him when needed!”
– Virginia
"We didn't start homeschooling until last year, my daughter's freshman year. I used a different math program that had come highly recommended and it was like pulling teeth to get my daughter to do her work. She said it was too confusing. This year we started with Thinkwell's Geometry and my daughter loves it. She can't believe how much better it is to understand. Now her math is done every day without being promoted. No more tears, no more fighting. Thank you, Thinkwell!”
