Nearpod Free App

I came across the Nearpod app. I haven't tried it yet, but I read many positive reviews for using this app in the classroom.
What is Nearpod?
On the itunes preview page it states that "Nearpod enables teachers to use their ipads to manage content on student iPads, iPhones or iPods. It combines presentations, collaboration, and real-time assessment tools."
Teachers share their slides with students and are able to control the pace of the lesson and monitor student responses.

1. Teachers can create content using various features available.
2. Share content with students to mobile devices.
3. Multimedia content engages students.
4. Teachers can see all student activity in real time.
