I wrote a post on my Maths Insider blog comparing Thinkster Math to Kumon Math®.
I used to run my own Kumon centre in the UK and 2 of my own children worked through the Kumon program for several years. I’m in a unique position to compare Thinkster’s innovative math program with the well-established Kumon program.
Thinkster covers a broader curriculum and improves analytical and critical thinking skills
One of Thinkster’s big benefits is that it gives more coverage of math content. Each worksheet in Thinkster can be mapped to the Common Core State Standards (CCSS) for Math. Thinkster students learn, not just computational skills, but analytical, logical reasoning, and critical thinking skills. These are skills needed to produce mathematicians, not just arithmeticians.

It’s great that a Kumon student often works above their school year level but in most cases, they can’t do anything outside of context and have weak analytical thinking math skills.
My 2 older students could manipulate complex algebra after several years of Kumon, which was indeed impressive, but still needed to build up their understanding of geometry, statistics, and the practical application of algebra. Thinkster builds these skills simultaneously.
Thinkster is flexible
We recommend that students complete 7-10 worksheets each week. Of course, 1 math worksheet every day is ideal, but we also know that “life happens”.
So, if a student wants to do 3 worksheets a day, that’s fine. And if a student only does 3 worksheets another week due to other commitments, that’s also okay.
In the Kumon math program, completing additional worksheets wasn’t encouraged, and completing fewer worksheets would likely result in plenty of repetition in the following weeks.
Thinkster encourages communication
This is where most people would think that Kumon would have a distinct advantage. Instructors meet their students face to face every week at the Kumon learning center.
