Algebra IAlgebra is a study of how the world can be modeled and interpreted by first quantifying it mathematically. To be able to communicate meaning effectively and form connections between concepts there is a need for proficient variable manipulation. Algebra I will develop skills in students to help them solve real world problems with a focus on:

(1) Write, solve, and interpret equations based on real-world situations and problems.

(2) Identify the rate at which data is changing by so that they may be able to predict future events.

(3) Create graphical representations of data to help communicate meaning and to identify solutions. Students will compare their graphs of data that changes at a constant rate to data that changes at other rates.

(4) Simplify algebraic expressions by extending the properties of numbers.(5) Find where two relationships are both true in order to find the values of

the unknowns.(6) Write inequalities to model real-world situations, find their solutions, and

interpret their meanings. An algebraic inequality is a relationship where the solution for an unknown is a range of values.
