Title: Polynomial Subtraction
Description:
Students will review the meaning of vocabulary relevant to subtracting polynomials such as opposites and the definition of subtract. They will be presented with examples of subtracting polynomials both vertically and horizontally. They will also be given ample opportunities to apply this new skill through game play.
Standard(s): [MA2015] AL1 (912) 10: Understand that polynomials form a system analogous to the integers; namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials. [AAPR1]
Subject: Mathematics (9  12)

Title: Conquering Polynomials
Description:
In this lesson, students will be introduced to polynomials. A polynomial is a made up of terms, which are algebraic expressions combined by addition or subtraction. In a polynomial, there is no expressions that involve dividing by the variable or taking any root of a variable.
