Algebra 1 Unit

(Solving systems of Equations and Inequalities)

By

J. Matt Tumlin

 

 

This unit plan is for an Algebra 1 class that uses contextual projects to help discover how to solve systems of equations and inequalities.Projects are included (in Microsoft Word) to help the contextual process.

 

Students will learn how to:

 

        Use graphs to model data.

        Graph a line.

        Graph a system of equations.

        Solve a system of equations by substitution.

        Solve a system of equations by elimination.

        Graph a system of linear inequalities.

 

Day 1:

 

How do you use graphs to model data?Use a classroom discussion to review graphs.For the SAT project, CLICK HERE.

 

Day 2:

 

How do you graph a line?Students will explore the slope intercept form of a linear equation.Individuals use what they have learned about linear equations to complete the Indy 500 project.For the Indy 500 project, CLICK HERE.

 

Day 3:

 

How do you graph a line (continued)?Students will explore the slope intercept form of a linear equation using technology.Groups use what they have learned about linear equations to complete the Wasting Water project.For the Wasting Water project, CLICK HERE.

 

Day 4:

 

How do you solve a system of equations by graphing?Students will explore graphing a system of equations by completing the Camperís Supply project.For the Camperís Supply project, CLICK HERE.

 

Day 5:

 

How do you solve a system of equations by substitution?Students will use a classroom discussion to explore the substitution method.

 

Day 6:

 

How do you solve a system of equations by elimination?Students will use a classroom discussion to explore the elimination method.

 

Day 7:

 

How do you solve a system of inequalities?Use peer coaching to complete the Flower shop project.For the Flower Shop project, CLICK HERE.

 

Day 8:

 

Spend the day reviewing the previous topics to prepare students for an assessment.

 

Day 9:
