## Reflection: Rigor The Tablet Wars: Comparing Linear Functions in Different Representations - Section 5: Exit Ticket and Homework

The Student Sample Writing about Multiple Representations is an example of how writing in the mathematics classroom can support students thinking and increase rigor and coherence, all aligned to the Common Core Content and Math Practice standards.

In this particular example, the student analyzes the three different companies and compares and contrasts the cost/benefit of investing in each company. One aspect of this activity that I have come to appreciate is the flexibility and differentiation that writing tasks bring to the table. Through writing, one student might work on understanding/identifying the big picture of the lesson, while another student focuses on providing more in depth analysis and justification of their writing.

In my classroom, writing is a main part of the daily routine and culture. I want students to be able to communicate and show AND explain their thinking not only through mathematical notation, but also through written language.
