I use this in my classroom and want to share it. However, I don’t use the method that the teacher below uses. Instead we had a class discussion about it. Then I had students cut out the three categories and glue them on the front and back side of an index card. I instructed them to keep this where ever they keep their library cards. That way, they could have it when they went to the library. Here is the Goldilocks Rule:
Second grade teacher Becky McCrary from Clear Creek Elementary in Hendersonville, NC, blended together Story Bits or Souvenirs with her instruction to make a great home to school connection with her students. (For more info on Story Bits, see my article by that name at http://www.teachers.net.) She taught the Goldilocks Rule for determining whether a book is too hard, too easy, or just right.
You can download the Goldilocks Rule Chart (2 per page to copy) and the Souvenir sheet (6 per page to copy) for your use.
