This is a tool that can be used for a quick assessment. I like this resource because it is a different engaging way to review previous material with students while giving me feedback on how well I am teaching. The basic premise of the tools is that it is an interactive quiz that the students take using different pixel images, that have been registered to their name. The teacher scans that pixel image to gather responses using an iPad or Android deviced. The students responses are then sent to the teachers home computer and formulated into reports that can be viewed as either class or individual student reports.
