Thanks to the wonderful website, wonderopolis.org, I simply project the "Wonder of the Day" picture (which is right there on the main page when you open the website) onto my white board and voila, the students can start jotting down their questions. Honestly, I did not do any kind of mini-lesson or pre-teaching about questioning, I just instructed the students to write at least 2 questions or more. Those lessons will come eventually. For those students who are unsure, start them with the prompt, "I wonder..." For IEP kids, you can have them copy one or more of the questions already provided under the picture.
These questions came from the "Wonder of the Day #1512: Where Is Shanghai?"
