If you are using iPads in the class room a great tool to use is a QR creator and scanner for students. You create a QR code by copying and pasting a link to a site in a QR generator and the QR image appears. Give students 4 or 5 codes to scan as they do independent work. This helps our kinesthetic learns try something more hands on.
Want to take it a step further? Create a gallery walk activity where students have to scan codes on posters around your room. The codes would take them to a site which would then be linked to an assessment that you hand them for completion
