Math 4 - Beginning Algebra I

Course Description:
Covers linear equations, linear systems, linear inequalities and quadratic equations in verbal,
numerical, graphical and symbolic forms . Also covers negative exponents, scientific notation
and dimensional analysis. Explores topics using a graphing calculator as well as traditional
approaches.

Performance-Based Learner Outcomes:
Upon successful completion of the course, students should be able to:
1. Create mathematical models of abstract and real world situations using linear
equations, linear systems, linear inequalities and quadratic equations.
2. Use inductive reasoning to develop mathematical conjectures involving linear equations,
linear systems, linear inequalities and quadratic equations. Use deductive reasoning to
verify and apply mathematical arguments involving these algebraic concepts . Be able to
distinguish between the concepts of inductive and deductive reasoning.
3. Use mathematical problem solving techniques involving linear equations, linear
systems, linear inequalities, quadratic equations and dimensional analysis.
Techniques include the use of tabular, graphical, symbolic and narrative
representations.
4. Make mathematical connections to, and solve problems from, other disciplines involving
linear equations, linear systems, linear inequalities, quadratic equations and literal equations .
5. Use oral and written skills to communicate about linear equations, linear systems,
linear inequalities and quadratic equations.
6. Use appropriate technology to enhance mathematical thinking and understanding, to
solve mathematical problems involving linear equations, linear systems, linear
inequalities and quadratic equations, and judge the reasonableness of results.

Course Content:
1. Number Sense: Describe recursive patterns in linear data. Solve linear equations,
linear systems of equations and quadratic equations from data.
2. Symbolism: Create a symbolic form of a linear equation in two variables from data
and graphs. Solve linear equations, systems of linear equations, linear inequalities and
quadratic equations symbolically and with the use of data tables and graphs. Solve
literal equations symbolically. Use the distributive property to change polynomials
from factor to term form and term to factor form. Model the distributive property as
area of a rectangle. Confirm and use the Pythagorean Theorem and its converse.
Develop the distance formula and the relationship of slopes of perpendicular lines
using right triangles.
3. Problem Solving: Apply appropriate mathematical concepts and mathematical
models, including linear equations, systems of linear equations, linear inequalities,
quadratic equations and dimensional analysis, to solve abstract and real world
problems.
4. Technology: Use a graphing calculator to investigate the nature of linear equations,
linear systems and quadratic equations. Use the graphing calculator to aid in
numerical calculations and decimal approximations.
5. Communication: Communicate mathematical ideas using appropriate terminology by
reading, writing, listening and speaking in group and individual settings.
