A math program based on a curriculum developed in Singapore has students in Skokie, Ill., schools spending less time on memorization and more time understanding the concepts used to solve equations. And they're doing it with more hands-on work, which has teachers noticing a more positive response from students so far this school year. "Our teachers keep telling us the kids get the math," said Laurie Heinz, assistant superintendent for instruction. "They understand how to do it, but more importantly, they understand why they're doing it. That's one of the things we love the most about this."
