(1) An eighth-grade student at the nearing proficiency level in mathematics demonstrates partial mastery of the prerequisite knowledge and skills fundamental for proficient-level mathematics. He/she:

(a) often uses incomplete and incorrect mathematical processes to solve problems, often inaccurately;

(b) communicates mathematical ideas, but often inaccurately;

(c) makes connections, but does not generalize and often his/her arguments lack appropriate supporting mathematical ideas;

(d) sometimes understands and correctly uses numbers, operations, patterns, relations, and functions;

(e) sometimes uses inaccurate or incomplete representations of rational numbers, proportionality, and algebraic concepts to solve mathematical problems;

(f) sometimes has difficulty recognizing complex measurement and geometric relationships and properties which result in inaccurate solutions; and

(g) makes simple predictions and decisions based on basic probability and statistics.
