Scoring Rubric
Task 1: New Swim Team
3 points: An efficient strategy is chosen, deductive arguments are used to justify decisions, student presents all work
clearly and precisely, and determines multiples, factors, and ratios.
2 points: A correct strategy is chosen, arguments are constructed with adequate mathematical basis, presents work
clearly, and determines multiples, factors and ratios.
1 point: A partially correct strategy is chosen, arguments are made with some mathematical basis, presents work with
some precision, partially determines multiples, factors, and ratios.
0 points: No strategy is chosen, arguments are made with no mathematical basis, presents work with little clarity and
precision, is unable to determine multiples, factors, and ratios.

Task 2: Championship Team
3 points: An efficient strategy is chosen, deductive arguments are used to justify decisions, student presents all work
clearly and precisely, and creates and successfully justifies an equivalent ratio.
2 points: A correct strategy is chosen, arguments are constructed with adequate mathematical basis, presents work
clearly, and creates and justifies an equivalent ratio with minor flaws.
1 point: A partially correct strategy is chosen, arguments are made with some mathematical basis, presents work with
some precision, attempts to create and justify equivalent ratios.
0 points: No strategy is chosen, arguments are made with no mathematical basis, presents work with little clarity and
precision, is unable to use two different strategies to solve the ratios problem.

Task 3: Comparison Shopping
3 points: An efficient strategy is chosen, deductive arguments are used to justify decisions, student presents all work
clearly and precisely, sets up equivalent ratios and uses a proportion to find the unit rate in order to compare the
prices among stores.
2 points: A correct strategy is chosen, arguments are constructed with adequate mathematical basis, presents work
clearly, and sets up equivalent ratios while recognizing the use of proportional relationships to find unit rates.
1 point: A partially correct strategy is chosen, arguments are made with some mathematical basis, presents work with
some precision, attempts to set up ratios while recognizing the use of proportional relationships cannot follow through
with a solution.
0 points: No strategy is chosen, arguments are made with no mathematical basis, presents work with little clarity and
precision, is unable to set up ratios and does not recognize the use of proportional relationships.
