## 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 Camper’s Supply project. For the Camper’s 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:**

** **
