Oh, hey! You found me! I was wondering if anybody looked at that little QR code in the corner!
If you made it to this corner of my internet, you must be doing your darndest to do the best of everything!
Now, then, how should we proceed? Reward? Bribery? Subterfuge? I vote the latter. Let's have some fun. Make sure at least a couple of people are watching as you scan the QR code (you may have to do it again). Then proudly announce, "NO WAY!" and run away and do something as if it is the most important thing in the world.
If you want to take this even farther, send me an e-mail and give me a new idea to continue this ruse. I will update the page to match whatever story you have created in the classroom.
Also, don't forget to get your actual work done.
