Angles that rotate is a new Geometry concept for my 3rd graders. We practiced drawing angles with different rotations and various angle degrees using straws and twist ties. I walked around with an iPad and used the camera feature to show students examples of what to do and what not to do. This showed up on the TV using Airplay. Then students did a "gallery walk" and silently observed their classmates angle rotations. Their mission during the "gallery walk" was to find an angle drawn correctly and an angle that needs some improvement and us their iPad and capture an images of these angles. They then imported these images into Explain Everything and described the angles. Next, volunteers used Airplay to share their findings with the class. Once students were put in a judging position by looking at their peer's work they were then able to better analyze their own angle rotations. To round up the activity students applied their improved understanding of angle rotations to their own work.
