# Beginning Algebra I

#### Prerequisites

MTH 20 or equivalent placement test scores

## Course Description

Covers the use of applications, formulas, and reasoning skills to write, manipulate, interpret, solve and graph linear equations and systems. Introduces concepts numerically, graphically, and symbolically. Develops skills to communicate results in oral and written form. Prerequisites: MTH 20 or equivalent placement test scores.

## Intended Outcomes

Upon successful completion of this course, students will be able to:

1. Use one variable to model and solve linear problems.
2. Use two variables to model and solve linear problems.
3. Communicate results mathematically and in writing.

## Outcome Assessment Strategies

Instructors will use a variety of the following measures:

• Homework, quizzes, group activities, problem sets
• Exams, which may include: proctored, take-home, open-book, group, cumulative
• Projects, portfolios, and field work - individual or group

## Course Activities and Design

This course will be delivered through a combination of lecture and student activities including group and individual problem solving during class. Emphasis is to be given to applications from outside the mathematics classroom. At least 2 hours per week must be set aside for students to work problems in class.
