Once finished, simply print out the QR code and place at the location of the center. In order for students to scan the code, you will need to have a device to scan it.
If you use a Chromebook, you could use a Symbaloo site like we do in the district where I work that includes a link to a QR code scanner readily available (https://the-qrcode-generator.com/scan).
The great thing is, students can listen to the directions multiple times if needed.
Of course there are so many uses that go beyond centers (lesson plans, positive messages to place around the school, etc) - but I hope this is something you enjoy.
Thanks to Dawn Montare for talking to me about QR codes the other day in the library! A simple conversation that hopefully now will have some legs! Thanks Dawn!
