I have been using iPads in my young, and very young learner classroom. Here’s the case I use to keep them safe. (I’ve also seen the same case in many photos and videos of kindergarten classrooms.) I like that its sturdy and can also be used to sit the iPad on the table at an angle, making it easier to use. If you use mobile devices in the classroom, I would also suggest demonstrating how to safely hold, and carry the iPad around the room.
