Google Jamboard is an online interactive whiteboard tool that can be used in so many ways. You can have all of your students interacting within the same slideshow at the same time.
Do you have students that don't have access to phones to upload their work to google classroom? This presents an alternative option for students to complete and share their work using Google Jamboard.
At times it can be handy for items to be locked in place. There is a way to do this using 'background images'.
