I saw this done in a social studies notebook and I really liked the structure. It is called a 3-2-1 review, which I have heard of before and use when kids are watching science videos to keep them engaged (list three things you learned, two things you thought were interesting, and one question you had). In this example of a 3-2-1 review for the notebook students drew a pyramid. On the bottom part of the pyramid the students had to list three facts. The second part of the pyramid they had to list two “whys” and at the top they had to write a summarizing sentence. I liked this as a right hand assignment. I have friends that are in an astronomy unit and they can use this structure to have children write three facts about the sun, two reasons why the sun is so important, and then a summarizing sentence.
