In a paperless classroom you can use Google Forms and a QR CODE generator to make sign in/out forms. The form will keep track of all students coming and going in the classroom. This is a basic sign in/out sheet with the option for adding a QR code to your digital version. For students who do not have a smartphone, this paper version offers a fast, easy solution! Check boxes also make it easier to track where students are headed. The form, which is editable, comes with directions for making a form and generating its QR code.
