What is a QR Code?

QR stands for Quick Response Code.
They are barcodes that link to text, a video, a website, launch a tweet, and more. 

I think I have seen these...

Yes, they have been popping up on posters, menus, etc... all around town.

How do you use them?

You need a smart phone with a QR code reader. (or an iTouch/iPad etc...)

Are these educational?

OF COURSE! Very. About half of all cell phone users already have smart phones and in just a short period of time almost everyone will. Take advantage of this emerging technology and include them in your classroom now!
