Use Google URL shortener. After you type in your website or blog address, choose shorten. Then click on Details next to the new shortened address. You will see the QR code. Copy and paste this to your picture file or Save As to picture file. Use your iPad or iPhone to read the code. You will want to get a QR reader app from iTunes. Then use the code for generating interest in your class website or blog. Use the QR code for students to search for information or do scavenger hunts. How fun is that? Be watching for some ideas for using QR codes in the classroom. I have been playing around with some lessons that use this unique technology.
