Math 6.4

Proportionality. The student applies mathematical process standards to develop an understanding of proportional relationships in problem situations. The student is expected to: (A) compare two rules verbally, numerically, graphically, and symbolically in the form of y = ax or y = x + a in order to differentiate between additive and multiplicative relationships; (B) apply qualitative and quantitative reasoning to solve prediction and comparison of real-world problems involving ratios and rates; (C) give examples of ratios as multiplicative comparisons of two quantities describing the same attribute; (D) give examples of rates as the comparison by division of two quantities having different attributes, including rates as quotients; (E) represent ratios and percents with concrete models, fractions, and decimals; (F) represent benchmark fractions and percents such as 1%, 10%, 25%, 33 1/3%, and multiples of these values using 10 by 10 grids, strip diagrams, number lines, and numbers; (G) generate equivalent forms of fractions, decimals, and percents using real-world problems, including problems that involve money; and (H) convert units within a measurement system, including the use of proportions and unit rates.
