- First, I downloaded a free QR Reader app on my smartphone. I have an iPhone, but it works as well on other phones.
- Then, I visited a free QR code generator site. On the site, I was able to write definitions, in Spanish, of the vocabulary. I wrote a description of the word, just as in the game Taboo, without mentioning the actual word, using circumlocution as I had had the students do in class the day before.
- I downloaded 10 of the definitions I wrote and the site generated a QR code for me. I then printed them out and hung them around the school.
- Next, the students were asked to download the free QR app on their phones. Some of their phones didn't allow them to download in the class and others did.
- I grouped the students who had the app with those who didn't. They were given specific instructions to scan the code, read the code and then move on to look for the next code in the hallway. They were also instructed to be as quiet as possible so as to not disrupt the other students in their classes. They were also told that this was a competition to see which group finished first and with the correct responses.
- After they found all 10 codes and scanned them, they were instructed to come back to class and in their group work out which word I was describing, without the use of their textbooks or notes.
