They are to pretend that the envelope represents the contents of a person's pocket, pocketbooks, briefcase, closet or inside of a room. They are to be ready to describe their person to the class and to tell the group why and how they made their decisions. This takes about 10 minutes. Then they share their results with the class. I end by telling them what they have done is called inference.
Inference requires that the reader go beyond the information an author provides in a text.
Then the class shares where they made inferences in that story. This lesson has been used from grades 7 - 12 . Hope you can use this.
