Lesson Plan : Solving Quadratic Equations

Teacher Name:
 Edmiston(Kellogg)
Grade:
 Grade 11-12
Subject:
 Math

Topic:
 Solving Quadratic Expressions using many methods
Content:
 Methods: Factoring, Completing the Square, Quadratic Formula, Graphing Calculator
Goals:
 Students will solve quadratic equations using various methods. Students will understand what their answers mean and the different possible types of answers we can have. Students will understand that some methods are more useful than others depending on the type of quadratic equation.
Objectives:
 The learner will solve quadratic equations by applying the zero product property The learner will solve quadratic equations by completing the square and the quadratic formula. The learner will solve quadratic equations by utliizing the graphing calculator.
Materials:
 SmartBoard, TI SmartView 84 Plus calculator emulator
Introduction:
 The class will begin with a warm up on simplfying quadratic expressions. Then, the students will be presented with a soccer problem that describes the path of the soccer ball and they will solve it to find out how long it takes to hit the ground.
Development:
 I will show the students that there are many ways to solve this problem. We will discuss the different ways that they came up with. Then I will tell them how some methods will allow us to solve all quadratic equations. I will chunk the different methods and allow time for the students to practice and solve.
Practice:
 Students will have 4 problems of each method to solve. I will place one on the board, walk around and help if needed, then show them how to do it. I will have students put their answers on the board.
Accommodations:
 It may be helpful to show students what the visual representation of quadratic functions look like and how where it crosses the x axis is where the solution lies.
Checking For Understanding:
 I will have students write on note cards a problem that they create themselves. They must really understand it in order to creat their own equation.
Closure:
 Students will have a summarizer problem that they must solve before they leave. It will be a tough equation and they will be able to use any method they want to sovle.
Evaluation:
 The students will have homework problems over solving and a quiz the next day.
Teacher Reflections:
 The students did great. I was only able to cover two methods because of time but the students really enjoyed creating their own problems. I should have started the soccer problem out using a graph instead of factoring. Overall, it was successful.
