Math teacher Marsha Ratzel experimented with a lesson on square roots to bring her math class closer to problem-based learning. Ratzel writes in this blog post that before teaching her students about square roots, she presented problems and had them research online and in class everything they could find about the function and discussed their findings. "And they really loved it. ... [T]hey argued and wrestled with all the info they collected and then built their conjectures," Ratzel writes.
