Students are transitioned from the emphasis placed on whole number arithmetic in the elementary grades to foundations of algebra. This course emphasizes rational numbers. Students will use ratios to compare data sets; recognize decimals, fractions, and percents as ratios; solve single-step and multi-step problems, using rational numbers; and gain a foundation in the understanding of integers. Students will solve linear equations, use algebraic terminology, and write inequality statements. Students will solve problems involving area, perimeter, and surface area, work with π (pi), and focus on relationships of congruence in polygons. Students will continue using the data cycle by applying it to circle graphs and developing concepts regarding measure of center. Ratios are used to compare two quantities and represent proportional relationships as a precursor to the development of the concept of linear functions. An advanced course is also available.
