## Reflection: Connection to Prior Knowledge Polynomial Quiz and Factoring Puzzle - Section 1: Warm up and Homework Review

This warm up demonstrates one of the most common conceptual errors students bring from arithmetic to algebra.  Students know that when you divide a number by itself the quotient is 1.  However, many don’t translate that understanding readily to situations with algebraic expressions.

My goal with a warm up like this is to use student work as way to generate class discussion, uncovering and correction the misconception.  Typically, someone will recognize and share that, when checking the work by multiplying, (see student's work) they do not come up with the original polynomial. This leads to the conclusion that there is a missing term, of 1 which is often left off (Math Practice 3).
