A great way to get kids learning independently is by using QR codes. Here, Matthew Bassett (aka @physedapps) shared his handywork: https://goo.gl/gxuQbi
It's easy to install a QR Reader on any Chromebook. Here are 2 terrific options:
ScanQR, an app.
Scan QR, an extension
Another suggestion, if you don't have time to print and cut the "cards", is to just put the links into Google Classroom. You can, then, have students view a specific chromebook for each skill (where the correct gif is playing). Obviously, it is important to have the Chromebooks in an area separate from where the dribbling will occur to avoid damage.
