3. Goals: Aims/Outcomes-
|
1. Students will solve quadratic equations using various methods.
2. Students will understand what their answers mean and the different
possible types of answers we can have.
3. Students will understand that some methods are more useful than
others depending on the type of quadratic equation. |
|
|
4. Objectives-
|
1. The learner will solve quadratic equations by applying the zero
product property.
2. The learner will solve quadratic equations by completing the square
and the quadratic formula.
3. The learner will solve quadratic equations by utilizing the graphing
calculator. |
|
|
5. Materials and Aids-
|
SmartBoard, TI SmartView 84 Plus calculator emulator, Worksheets |
|
|
6. Procedures/Methods-
|
A. Introduction-
1. The class will begin with a warm up on simplifying quadratic
expressions.
2. 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. |
|
|
B. Development-
1. 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.
2. I will tell them how some methods will allow us to solve all quadratic
equations.
3. I will chunk the different methods and allow time for the students
to practice and solve. |
|
|
C. Practice-
1. Students will have 4 problems of each method to solve.
2. I will walk around, assisting when necessary.
3. When students have finished, I will call on students to write their
answers on the board.
4. We will go over the problems together. |
|
|
D. Independent Practice-
Students will complete a worksheet. |
|
|
E. Accommodations (Differentiated Instruction)-
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. |
|
|
F. Checking for understanding-
I will have students write on note cards a problem that they create
themselves. |
|
|
G. Closure-
Students will have a summary 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 solve. |
|
|
7. Evaluation-
|
1. The students will have a worksheet to complete.
2. There will be a quiz on the covered material the next day. |
