Hamilton High School math teacher Nick Schweitzer admits he isn't the best visual learner.

"For me, I know that 3D math is hard to visualize, I don't see pictures in my head," he explained.

To help students like him in his AP Calculus class, Mr. Schweitzer introduced a lesson with playdough and dental floss to teach an introduction to cross sections.

"The hope was to experience the 3D cross sections in a tangible way," Schweitzer said. "It's a great way to help them be kids at heart but also learn some cool calculus along the way."

With the AP Calculus exam coming up, Schweitzer is confident a fun lesson like this will help the content stick.

"When they see a question or two like this on the exam, hopefully they can visualize back to the playdough experience and that will help them tackle the problem."
