Think about it. Writing gives a voice to every student. How powerful is that?! Consider writing open-ended questions with multiple entry points when creating prompts and/or questions for students to respond to. In this way, all students have access to the task. Keep them short. Consider the following: Recap today's lesson. Can you say it in 6 words? Think about how selective students will need to be in choosing their words. With a quick glance, you can see which students got the gist of the lesson. Purposeful questions foster students' reasoning of mathematical concepts.
Or, use the math prompts/questions as exit tickets. Exit tickets set an expectation that students need to be actively involved during the lesson to be able to demonstrate their understanding in a thoughtful way. Students can be given time at the end of the class period to synthesize the day's lesson by completing an exit ticket. Once the exit tickets are turned in, information can be gathered to guide instruction the next day.
