Algebra IA is the first half of a two-year study of Algebra I. The year starts with studying variables, patterns and graphs. The order of operations is reviewed using expressions that include variables. The measures of central tendency are taught using relevant data.  The course continues with the study of rational numbers and the properties that govern them.  Emphasis is placed on why these properties are important and where and when they are used to help in solving all equations. Throughout the remaining part of the year the two basic concepts of solving and graphing are taught in a variety of ways and situations. Students start by solving single step equations and move through multi-step equations, solving equations using the concepts of ratio and proportion and similar figures. The students will be able to use the Pythagorean theorem to help solve equations in finding the missing side of a right triangle.  They will also be able to solve inequalities and problems involving absolute values, and understand one-dimensional and two-dimensional graphs to aid in solving inequalities. The year ends with combining the student’s knowledge of graphing and solving as they learn to solve systems of equations. Throughout the curriculum the students apply their skills to solve word problems including consecutive integer problems, motion problems, value problems and problems involving percent change.
