# Unit Introduction

In this lesson students will be introduced to parts of a quadratic function on a graph. The teacher will have a discussion with students about quadratic functions and the different methods that will be used in this unit to solve quadratic equations. The teacher will introduce a vocabulary foldable.

Lesson 1

1. Notes on Quadratic Functions and Equations

2. Vocabulary Foldable

# Solving Quadratics by Factoring

This is a way for students to review trinomial factoring. They will create a foldable to help organize their thinking and use it to recall process steps in factoring. This foldable can be used as a guide throughout the unit.

Lesson 2

1. Notes Solving Quadratics by Factoring

Day 2 Guided Practice/Independent Practice

2. Factoring Foldable

# Solving Quadratics by Graphing

This lesson is a three step process. The student will compare factoring, graphing the function without a calculator and finally graphing the function with a graphing calculator to check their work. The teacher will guide the students through notes and then assign independent practice.

Lesson 3

Notes Solving Quadratics by Graphing

Day 1 without using a Calculator – Guided Practice & Independent Practice

Day 2 with a calculator – Same Guided Practice & Independent Practice w/cal.

# Solving Quadratics by Completing the Square

In this lesson, the teacher will lead the student through a series of steps that explains the process for solving quadratics by completing the square. The teacher will guide the students through several examples and then the student will work on several problems independently.
