Mr. D Math is an online math program for homeschoolers in grades 5-12. It emphasizes understanding concepts rather than just memorizing. Founded by Dennis DiNoia, it offers accredited courses that count towards transcripts.

Research from the National Home Education Research Institute (NHERI) shows that homeschooled students typically score 15 to 25 percentile points higher than public school students on standardized academic achievement tests. Studies show that homeschooled students are accepted to college at rates comparable to or higher than their traditionally schooled peers, and they tend to earn higher GPAs in their first year of college (Journal of College Admission, 2010).

What is Mr. D Math?

Mr. D Math is an accredited online math program made for homeschoolers and independent learners from grades 5 to 12. Dennis DiNoia, who has taught math since 1988, started it to help students grasp the 'why' behind math, not just the 'how.' The program is WASC-accredited, so courses count on official transcripts. Most teachers have over 10 years of experience and go through a tough two-year certification.

Courses and options

Mr. D Math offers a range of courses: Pre-Algebra, Algebra 1, Geometry, Algebra 2, Pre-Calculus, and Calculus I (NCAA approved). Beyond math, there are classes like SAT/ACT Bootcamp, Consumer Math, American Sign Language, Economics, and Digital Music Production. Students can choose self-paced courses for $197 a year, letting them watch lessons and learn at their own speed. Live classes cost $290 a year in 10 monthly payments and offer real-time interaction and support.

Teaching approach

What makes Mr. D Math stand out is its focus on understanding concepts. Students learn why math works, not just how to use it. Fun video lessons use humor and props to explain ideas. Each problem comes with detailed solutions, which is a big plus compared to traditional textbooks. Tests can be retaken with notes, reducing stress. Plus, a new gamification system with points and badges keeps students motivated.

What parents say

Parents love how Mr. D Math helps kids who previously struggled with math. Many kids actually start to enjoy math after using this program. The relaxed teaching style helps ease math anxiety. Step-by-step solutions are especially valuable for independent learners. A few parents mention that some teachers speak quickly, which could be challenging for some learners. Families can try it out risk-free with a 30-day money-back guarantee. Discounts are available for families with multiple students or returning learners.

The bottom line

Mr. D Math is a great option for homeschool families looking for quality math instruction without having to teach it themselves. Its focus on understanding, engaging teaching style, and thorough solutions support independent learning well. It’s especially helpful for students who have had a hard time with math before. Plus, the WASC accreditation adds credibility for college-bound students. Check out the 30-day guarantee at mr.dmath.com to see if it’s a good fit for your child.

Co-founder, BetterSchool

Lisa is the co-founder of BetterSchool and a homeschool mom of three. BetterSchool administers the largest independent homeschool community in the country — over 350,000 families across all 50 states.

When COVID hit, Lisa and her husband pulled their children out of school and hit the road. Homeschooling wasn't the plan — it was a necessity. But somewhere along the way, the family fell in love with it: the time together, the ability to tailor lessons to each child's interests, learning at their own pace, the freedom to travel, eating healthy on their own schedule, and the countless other benefits that come with homeschooling.

As they traveled, Lisa kept discovering incredible hands-on learning experiences that most homeschool families had no way of finding. She built BetterSchool to make it easy for every family to find and book the experiences that make learning come alive.

Through her community, Lisa has helped hundreds of thousands of parents navigate homeschooling, while also helping local businesses find and serve the homeschool community. She is the former managing partner of a law firm focused on business law and mergers and acquisitions — BetterSchool is her second technology startup. She holds a J.D. from California Western School of Law and a B.A. from Penn State.
