Today is a beautiful day outside here in South Korea, and the students were just coming back from a long vacation. We've been working hard in class lately, so I decided to give the students a bit of a break. I made a Picture Quest and put them in teams of 5 or 6 people. I shared the link with them on Twitter and they could download it onto their phones. I flashed it up on Powerpoint and explained the purpose and the rules. Then, I gave them 5 minutes to make a plan and translate anything that they needed to, as well as ask me any questions. And then I sent them off.
Essentially, the students have to take pictures of all the things listed as quickly as possible and the first (second/third) place teams to come back, get a prize of some sort. And...it worked really, really well. Like this class that I just had is generally unenthusiastic about anything, but they really enjoyed it! Success! However, I'm not sure I would necessarily do this at a public school or hagwon. I'm lucky at my job in that nobody is looking over my shoulder at what I do and it's fine to send students outside for some fun on a nice day.
