321 Summarizer

Materials Needed

Scratch paper or index cards


The 321 designates how many of each kind of summary statement or item the student is to construct. Students are asked, at the end of class, a reading, movie, etc., to write down: 3 things/ 2 things/ 1 thing. You can use headings like: Interest, questions, rules of the game, ways to use, factors, things you already knew, things you want to learn more about, etc. as the 3-2-1 headings.


This structure is helpful in assisting students in summarizing their thoughts and/or questions. It also allows students to consider the application of new learning. It is not necessary to collect the 3-2-1 summarizers, but collecting them can give the teacher some valuable information regarding student knowledge and understanding.
