Most days after school, sophomore Jimmy Lapsley heads to a Lakeville strip mall not to grab dinner or pick up his dry cleaning, but to brush up on math skills.
This fall, Lapsley was "pretty much failing geometry" — but since coming to Mathnasium, a private tutoring service specializing in math, he's been getting A's and B's, he said.
"The way my teacher was teaching it wasn't really clicking," he said.
Mathnasium is one of several national companies that aim to improve kids' academic skills — if their parents can afford to pay for the extra help.
There are 17 Mathnasiums in Minnesota, including a Shakopee location that opened six weeks ago.
Of the 440 Mathnasium franchises across the country, 100 were added last year, said Vance Fiegel, the Shakopee location's owner and director.
It's all part of the growing "supplemental education" industry, which includes competitors Sylvan, Huntington and Kumon.
The tutoring and test prep market — which brings in $5 billion to $7 billion annually — has been growing for more than a decade, with steady growth since 2010, said Steve Pines, executive director of the Education Industry Association.
