The comprehension questions are designed to follow along with the story. Each question is made to be a Higher Order Thinking question. This is so students are thinking at higher levels. Also at the end of each comprehension question packet it asks the students to make up their own HOT question using their HOT question packet. This is something you can choose to use or not. I have found that it is one of my students favorite parts, since it allows them to create their own works. I then allow them to display and answer each others' questions, in a gallery walk.
All answers are in the teacher's manual for Reading Street.
