Math Writing gives students time to explore numbers, solve problems, and explain their mathematical thinking. Before students begin practicing independently, they need a clear understanding of what Math Writing looks like and how to be successful.

In this classroom video, Karen introduces Math Writing by connecting it to activities her students already know and the foundation lessons she already taught, including math journals, workbook problems, and Number of the Day. She helps students recognize that explaining their thinking is an important part of being a mathematician.

Karen then guides students through creating an I-chart, identifying the teacher's role and the behaviors students will practice to build independence. Together, they establish expectations for getting started quickly and quietly, staying engaged in math, using an appropriate voice level, and building math stamina.

Notice how Karen connects these expectations to routines her students have already learned through Daily 5 and Math Daily 3. She also makes room for student thinking, discussing practical ways to manage distractions and choose a workspace that supports learning.

By taking time to explicitly teach these behaviors, Karen prepares students for meaningful independent practice while creating opportunities for her to work with individuals and small groups.

As you watch, notice how Karen involves students in defining what independence looks like and helps them understand the purpose behind each expectation.
