Help your students understand the difference between a surface level question and a question that requires more thought. These questions are often referred to as Thick or Thin questions. Using the cards I've made have the students read the question to a friend and then they ask them if the question is a Thick or Thin question. After they've each read their card to each other and discussed their answers, they trade cards and find another friend to read their new question to. These cards can also be used in centers, Daily 5, or groups.
