I read the first stories aloud. I pick my story based on what's available in single copies from the library or my personal copies. I don't read the version that I have multiple copies of to the students. I save that one for tomorrow. Then I read another traditional Gingerbread Boy Story that has different information under some of the headings.
Some information is the same.
After reading the second version, we fill in more information under the headings. Sometimes, depending on the class, I stop and fill in under the headings as they find the information. Sometimes I put a sticky note if a child finds something. I usually try and read straight through so the kids who aren't familiar with the story get the flow of the story. On Day one I have the kids help retell the gingerbread story.
