Consider this picture. Think you could come up with something to say about it in your students’ target language? Think you could ask questions about it that your students could answer? I know you can.
A quirky picture is just the thing for getting a lot of bang for your buck when you want students to get lots of interesting input in the target language and, eventually, to say interesting stuff in the target language. I especially recommend asking questions, starting with factual questions about the picture (How many port-a-potties are there? What color are they?) and moving on to extension questions allowing students to invent details and context (How old is the teddy bear? What was the teddy bear doing in there? What kind of event is this? Where will the teddy bear go next?) and personal questions about students’ relationships to concepts in the image (Have you ever seen something unexpected emerge from a port-a-potty? How do you feel about port-a-potties? Would you let your teddy bear in a port-a-potty?)
Websites with free stock photos are a superb source of quirky images. Most of mine, including those on this page, come from gratisography.com.
Edit 04-20-2020: David from pikwizard.com has just made me aware of that site, which specializes in photos featuring people and looks great.
Grab a stock photo and have fun!
