John Bennardo is challenging students at the Turtle River Montessori School in Jupiter. He created The Container App, which is free. It makes the art of solving math problems fun.
"I've always been interested in games. I love apps and playing games and it's always been a part of me," said Bennardo.

He knows kids love them too.
The school invited him to the classroom to add another dimension to learning math.
Karen Asofsky, the head of the math department there said, "We do even hands-on learning on the play yard using geometry and trigonometry to calculate measurements of things on our playground. This is the kind of thing we do all of the time, so we love it."
Bennardo said adults can enjoy the app as well.
"They can work with their parents. I've heard people sitting together as families trying to come up with the answer," said Bennardo.
He is using his app to encourage kids not to give up when the math problem is challenging. Bennardo is also using his life story. When he was 16, he was diagnosed with sarcoma, a cancer in his leg.
"You set your mind to it, and you can accomplish it, and I beat cancer," said Bennardo.
He says he will be donating part of the proceeds from the app to the Josh Powell foundation, which helps families and patients battling sarcoma.
