Google Forms – by using the add-on called Choice Eliminator 2, you can use Google Forms as a sign up sheet (parent conferences, class parties, etc.). Choice Eliminator will eliminate choices as people sign up for them.
Google Slides – Try thinking of Slides not just as a slideshow tool, but a way to create an interactive digital poster. It is easy to drag, drop, and rotate different text, shapes and pictures. It is also easy to insert YouTube videos and charts from your Google Sheets.
