I have come across some ways to create QR codes - different apps and websites, and also using Google docs. Today I came across Tammy Worcester's blog that explains how to create QR codes using Google docs - specifically using a spreadsheet. I thought, "Here it is! Here is the place where I will be able to create text for a QR code with math symbols."
Here is what my test run spreadsheet looked like:
It didn't work as I had hoped. Bummer. When I scanned the top QR Code, the word "hello" showed up without a problem. When I scanned the bottom QR Code, this is what I saw:
So, I am back to the drawing board and will continue my search to integrate math with QR codes. If anyone out there has any ideas or thoughts on this issue, I would love to hear from you.
