The document is perfect for a reading assignment. There are boxes for the students to fill in some notes that they think are important for reading as well as a box to ask a question that they are still unsure about. I have used this for homework to guide the discussion the next day. However, it can also be used at a center or a class activity before a discussion.
If you have any other ideas along these lines, that you would like me to create, please feel free to message me and I will try my best to help you out!
