This is a technique you can use in your class to help with inference development and a myriad of other skills that you can tailor. For example, with the photo included, you might ask student to write questions that are generated from either the man's point of view or even the dog's point of view. The type(s) of picture(s) you select can make all of the difference in the targeting students' focus to a particular skill ( i.e. setting, plot , lighting, etc.) or even question type. Wow, you could even require students to post questions that include specific vocabulary terms. I have even used this strategy as an intro activity with photos that are related to a new unit. The possibilities are endless.
I use this with a number of photos in a gallery walk style. All you need are printed pictures, sticky notes, and pens.
