### Lesson Plan

## Factoring Polynomials by ECSDM

### Grade Levels

Commencement, 9th Grade

### Description

In this lesson, students will review multiplying two binomials together (FOIL) in the "Do-Now". Students will then learn how to factor a quadratic equation in the form of x^{2} + bx + c, when a is equal to 1.

### Website(s)

### Objectives

Through the interactive SMART Notebook lesson, the students will:

^{2}+ bx + c, when a = 1 into 2 binomials

### Duration

Two 45-minute class periods

### Materials/Web Resources

- Computer
- SMART Board
- LCD Projector
- "Factoring Polynomials" worksheet
- Internet Game - Rags to Riches

### Procedure

**This procedure should be used in conjunction with the SMART Board file available below.**

*Day 1* -

- Have students complete the DO NOW which consists of practicing the FOIL (first, outer, inner, last) method. This will help them to understand that factoring is foiling backwards.
- Go over the DO NOW with the students. Reveal answers by removing rectangles.
- Have students copy down notes on factoring polynomials.
- Go over a few examples with the students. Use the box on the side to drag over needed numbers and operators. Follow the steps that are listed on the notes page.
- Ask students to try a few problems in their notebooks. Have a few volunteers come up and complete the problems on the SMART Board.
- Hand out homework worksheet ("Factoring Polynomials" worksheet below.) Have students begin problems in class and finish for homework.

*Day 2* -

- Go over homework with students. Have a few volunteers complete the problems on the board or SMART Board.
- Go to the Rags to Riches game which can be found at quia.com.
- Have students complete each problem on a separate sheet of paper that will be handed in. As a class, vote for the answer.
- Continue until game has ended.

### Assessment

- Students will be assessed on participation in the SMART Notebook lesson.
- Homework assignment will be checked. See attached sheet with answers.
