Pre-Algebra [Competency Based] (2nd semester)

Course Description\nPre-Algebra helps students make a successful transition from arithmetic to algebra by focusing on basic concepts of arithmetic and the applications of mathematics. Students learn about integers, fractions, decimals, expressions, equations, ratios, proportions and percentages, inequalities, graphing, probability and statistics, and geometry. The course highlights the math skills needed to be successful in everyday life and prepares students for future mathematics courses.\n\nCourse Breakdown\n\n Ratios\n Unit rates\n Proportions\n Percentages\n Sales tax and price\n Commission\n Simple interest\n Compound interest\n Inequalities\n Compound inequalities Pictographs\n Bar graphs\n Histograms\n Circle graphs\n Equations in two variables\n Graphing linear inequalities and equations\n Slope-intercept form\n Scatter plots\n Mean, median, and mode\n Box-and-whisker plots\n Stem-and-leaf plots\n Independent and dependent events\n Length\n Time\n Converting between US and metric measurements\n Lines and angles\n Complementary and supplementary angles\n Perimeter, area, surface area, and volume\n Polygons\n\nCourse Goals\n Recognize and represent proportional relationships between quantities.\n Represent decimals, ratios, and proportions as percentages.\n Perform calculations using percentages.\n Write and solve linear inequalities.
