As we know, formative assessments are a great way to drive instruction. Using immediate, on-the-fly checks for understanding can steer a lesson in a matter of seconds, and also help teachers form differentiated groups quickly and efficiently.

Teachers can also push their whiteboards out to students, who can then edit them. Check out this quick video to see all the neat things it can do!
