I have created two templates for summarizing strategies. The ticket out the door and the 3-2-1 Pyramid! Feel free to download them and use them in your classroom.
The ticket out the door is a great way for students to summarize what they have learned, answer a question, and/or ask you a question.
The 3-2-1 Pyramid is a great strategy to use in which students list 3 things they learned, 2 interesting facts about what they learned, and 1 question they still have.
