We expect certain professionals to go above and beyond just showing up for work. Educators are good examples of this. They are the backbone of our society and we rely on them to prepare the next generation of entrepreneurs. Mathnasium is an unintended result of going above and beyond, and it provides some clues about how to strongly start any business.

Ranked #3 on Forbes list of Best and Worst Franchises to Buy in 2016 for investment under $150,000, the Mathnasium franchise model has enjoyed success since it launched in 2002. It currently has more than 700 locations with an average of two new openings each week.

What started as a need to help students in the inner city of Los Angeles has become one of the fastest growing franchises in the United States.

The journey begins in the inner city

“I started teaching in 1974 at an inner city junior high school in Los Angeles,” says Mathnasium Founder Larry Martinek. “I quickly came to realize that not only were too many students leaving elementary school several grade levels behind, but even those working close to grade level lacked Number Sense – the ability to see numbers in perspective.”

Martinek began picking up the slack from traditional education and created supplement material to help fill the gaps for students. It wasn’t until his son, Nick, came along in 1980 that he realized he needed to take it a step further. “By age four, Nick displayed a strong bent toward math and logic,” Martinek recalls. “By age six, he was conceptualizing math that was beyond his years. As a result, I had to find ways to explain serious math to a very young child.”

Martinek admits that his son altered his own thinking about education. “This changed my own approach to thinking about and explaining math to other people.” He began working with Nick to develop supplement materials he could use in class to help teach the same to students. According to Martinek, helping his son was not his only goal. “My motivation was two-fold: first to educate my son, and second to educate everyone’s sons and daughters.”
