New Approaches to teaching fractions [Article]

For the parents struggling to teach fractions, research suggests using pies isn’t necessarily the best way:

The networked society that we live in today may feel radically different, but many youth are struggling with the things they’ve always struggled with.They’re trying to figure out who they are and how they fit into the bigger world. They want to hang out with friends, but they’re also trying to figure out the status games of their peers.
