Gimme 20!

For this activity (and for the others), you’ll need to find the right photo first. There are countless websites offering stock images and digital photos, but I recommend using the Creative Commons search tool. With this tool, you can search for images on Flickr, Google Images or Wikimedia Commons, use them in your ESL classroom, and rest assured you won’t be violating any copyright laws. Search for an image that conveys feelings or a mood you wish to explore. I found this one on Flickr. Show this image to your class and ask them to brainstorm and come up with 20 words related to this image. When they’re done brainstorming, they must place these words into categories, for example, “feelings”, “colors”, “nature”, etc.... Finally, give them a writing assignment to complete in class or for homework, like a story based on the photo, in which they must use the words.
