Introduction
This lesson will cover all the basics for understanding
and graphing linear equations. It has several activities designed to
bring the student to standards proficiency regardless of previous experience or
knowledge.
Subject: Algebra IStandards Addressed
Topic: Graphing Linear Equations
Grade Level: 9th through 12th
Student Lesson Home Room
California Mathematics Standards
Grades Eight Through Twelve
Algebra I
6.0
Students graph a linear equation and compute the x- and y-intercepts(e.g., graph 2x + 6y = 4). They are also able to sketch the region defined
by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).
Given a sheet of graph paper and a linear equation:
- Student will construct a coordinate grid system on the graph paper and will have all appropriate labels, including the x and y axis, origin, dimensions, equation, and points.
- Student will recognize, understand the importance of ( in relation to a linear equation), and plot ordered pairs on a coordinate grid system.
- Student will connect plotted points to show line or inequality.
- Student will be able to identify the slope, x and y intercepts, and give an example of real world application of these properties
Introductory Activity
Students are to take a pretest to ensure that they know how to do basic activities associated with graphing a linear equation. These items that they should know are:
* Construct a coordinate grid system with appropriate labels
* understand the function and use of an ordered pair
* Plot an ordered pair on a coordinate grid system
* Understand the function, different forms, and use of a linear equation
* Solve an equation for a given variable using Algebraic techniques
If the student is not familiar with one/or any of these tasks, they may review that task by clicking on the key words for it.
Enabling Activity
Students should read appropriate material relevant to the lesson before class begins.
Vocabulary associated with this lesson should also be familiar and understood by the students.
Linear Equations:
Standard form
Slope-intercept form
x/y tables
Pick an x value
Solve for y
Plot the ordered pair
Connect the dots (use a straightedge)
Culminating
Activity
The students will be required to do a web-quest investigation to find
different, real world examples of uses of a linear equation and be able to
explain the properties of a linear equation in relation to their real world
example.
Assessment
Insert your grading rubric for the culminating activity or a link to your rubric or test document file. Results
After implementing your lesson (sometime between January & March), insert a chart of your pre-test, post-test, and culminating assessment data.
