Number talks have become a best practice in many math classes in recent years and for good reason! They provide children (and adults) with an opportunity to deepen their understanding of math concepts through active communication with other. In a number talk people articulate and defend their ideas and analyze the reasoning of others.

There are a number of great sites to get images for number talks from. We've compiled a number of them (and cited our sources) to create a handy, organized number talk slideshow available for FREE download.
