3-2-1

This writing activity enables students to summarize their understanding of material, to evaluate understanding for gaps in knowledge, and to communicate this to their teacher.

3-2-1

Summary

Students reflect on their own knowledge using a writing strategy that asks them to identify the things they have learned and questions they still have. The first question results in three responses, the second question results in two responses, and the last question results in one response. Though this strategy can be used at any point in the lesson, it makes for an ideal exit ticket, showing educators both the information that stuck as well as the holes students felt they had in their understanding of the material.

Procedure

  1. Present students with the writing prompt: What are three things you learned? What are two questions you still have? What is one thing you found interesting?

  2. Have students answer the questions and either share out their responses or turn them in.

  3. Consider watching the K20 Center's "3-2-1" video for more information.
