I repeat: The first time you take a picture on the Chromebook, let it be the only thing that you do on the project and take a break. You can add more later, but taking a picture for the first time is difficult for the students. When you insert an image into Google Drawings, you choose the option to Take a Snapshot. In order to use the camera, you have to allow the program access to your camera not once but twice. See the images below (both images will pop up, but students have to hit allow on both for the camera to work).
This project will be part of a Who Am I? class book that the students are making. The first page tells riddles about the students; the second page shows a picture and the student's name. Usually, the students draw a picture of themselves on paper; however, I thought this would be the perfect chance to teach the students how to use the camera on the Chromebook. Here is an example that I created. You will see my lovely face as an example because I have not asked for parent permission to use student images on my blog (yet). Enjoy!
