Anyways, QR codes are those little black and white boxes that you can use a scanner to read. A scanner can be anything from a smartphone, to an iPod, or an iPad. These codes are linked to information; be it a website, directions, contact info, or just dialing a phone number (only while using a smart phone.)
So many classroom applications! I already added one to my classroom website, and am putting it on my classroom info magnets for the parents this year. I love the idea of sending the kids on scavenger hunts (using iPods as scanners) looking for information and clues. The possibilities truly are endless, and limited only by your imagination.
I used www.snapmaze.com to create my QR codes--it was simple, and all I had to do was save the code as a .png file to use it. You can download free scanners to your device--just do a search in the app store for them.
Just for giggles, here is a QR code to take you to Lynda's blog, orjust click the button below to take you to her awesome blog! Happy coding!
