Rubrics

(7)

[ 4 ] $28,000, and appropriate work is shown, such as showing that paper is of the total budget and utilities is , and the difference between the amounts is found correctly.

[ 3 ] Appropriate work is shown, but one computational error is made.

or

[ 3 ] The dollar amounts for paper ($36,000) and utilities ($8,000) are found correctly, but the difference between the amounts is not found.

[ 2 ] Appropriate work is shown, but two or more computational errors are made.

or

[ 2 ] Appropriate work is shown, but one conceptual error is made.

[ 1 ] The dollar amounts for paper and utilities are found using an incorrect method, but the amounts are subtracted appropriately.

or

[ 1 ] It is stated that paper is (or an equivalent fraction) of the budget and utilities is (or an equivalent fraction) of the budget, but the dollar amounts and their difference are not found.

or

[ 1 ] $28,000, but no work is shown.

[ 0 ] A zero response is completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by an obviously incorrect procedure.

(8)

[ 4 ] y = –x + 2, and appropriate work is shown.

[ 3 ] Appropriate work is shown, but one computational or graphing error is made.

or

[ 3 ] The correct slope and intercept are found, but no further correct work is shown.

or

[ 3 ] A correct equation is written, but it is not expressed in slope-intercept form.

[ 2 ] Appropriate work is shown, but two or more computational or graphing errors are made.

or

[ 2 ] The correct slope is found, but no further correct work is shown.

or

[ 2 ] The line is graphed correctly and the y-intercept is identified correctly, but the correct equation is not written.

[ 1 ] y = –x + 2, but no work is shown.

[ 0 ] A zero response is completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by an obviously incorrect procedure.

(9)

[ 4 ] The table is completed correctly and a cumulative frequency histogram with appropriate labels and scales is constructed.

[ 3 ] The table has one or two errors, but an appropriate cumulative frequency histogram is drawn.

or

[ 3 ] The table is completed correctly, but one error is made in drawing the cumulative frequency histogram or one or more labeling errors are made.

[ 2 ] The table is incomplete, such as the frequency column is not filled in, and one error is made in constructing the cumulative frequency histogram.

or

[ 2 ] The table is completed correctly, but one conceptual error is made, such as constructing a correct bar graph or frequency histogram.

[ 1 ] The table is completed correctly, but no further correct work is shown.

[ 0 ] A zero response is completely incorrect, irrelevant, or incoherent, or is a correct response that was obtained by an obviously incorrect procedure.
