(1) The benchmark for mathematics content standard 1 for a student at the end of grade 8 is the ability to:

(a) recognize, model, and compare different forms of integers and rational numbers including percents, fractions, decimals, and numbers using exponents and scientific notation;

(b) select and apply appropriate estimation strategies to judge the reasonableness of solutions to problems including those computed on a calculator; and demonstrate correct use of order of operations;

(c) use number theory concepts such as prime factorization, greatest common factor, and least common multiple in problem situations;

(d) compute fluently and solve multi-step problems using integers, fractions, decimals, and numbers in exponential form;

(e) use metric and standard units of measurement in relevant scientific and cultural situations, including those of Montana American Indians, compare and convert within systems, and use appropriate technology; and

(f) understand and apply proportional relationships to model real world situations and to solve problems involving rates, ratios, proportions, percents, and direct variation.
