For this story, I would use a cause and effect worksheet for students to fill out with me after reading this story in whole group. Cause would be on one side and effect would be on the other. Some blanks would be filled in for the students to help them and give them some examples. For example, one cause would be "the cows were cold at night," and the students would have to fill in the effect. I would use this activity after teaching the students the meaning of cause and effect. I would use this in a second or third grade classroom.
