Reflection: Writing Across the Disciplines Uses of Polynomial Division- The Factor and Remainder Theorems - Section 1: Warm Up and Homework Review


There is definite power in having students write their own steps or procedures for a skill in algebra.  This is one big shift that I have pushed a lot this year.  Rather than telling a student how to do a skill, we develop it conceptually, practice it using guided practice, and then I have the students write their own summaries in their notes.  Today’s warm up uses this idea to check on their understanding of dividing a polynomial through synthetic division.  Here are several samples from my class; Warm Up 1, Warm Up 2, and Warm Up 3.  I really like how the responses can vary so greatly and it is easy to diagnose conceptual issues from an exercise like this.
