The score is found by adding the number of points for each measurement.

Four trees and their measurements are given below.

Points Student Response

2 The focus of the item is to determine the hours worked from a time card and calculate the weekly wages. The response determines Helga worked 15.5 hours and earned total wages of $97.65.

1 The response provides evidence of a partially correct answer and/or solution process. The response shows understanding of some key elements of the task but contains gaps or flaws.For example, the response may:

• Identify the correct number of total hours worked, but fails to find the total wages.• Determine the total wages based on an incorrect number of hours (e.g., ignoring the fractional parts of hours, rounding off hours, or miscalculating.) However, this number is multiplied by $6.30 to obtain the total wages based on the incorrect number of hours.• Contain a detailed explanation of the steps required, but has incorrect or missing totals.• Only state Helga’s total wages are $97.65.

0 The response indicates inadequate understanding of the task and the response does not meet the criteria required to earn one point.For example, the response may:

• Include unrelated statements or work.

2 The focus of the item is to sketch a net of a triangular prism with given dimensions. The response shows a sketch of a net with dimensions labeled appropriately.

1 The response provides evidence of a partially correct answer and/or solution process. The response shows understanding of some key elements of the task but contains gaps or flaws.For example, the response may:

Contains a correct net but one or more of the dimensions is labeled incorrectly or missing. Contains a slightly flawed net (e.g., the student may omit the second triangle, or place the rectangles in an order that does not correspond to the order of the sides of the triangle.)

4 The focus of the item is to calculate scores based on tree measurements, order these scores from largest to smallest (or smallest to largest) and determine a general formula to calculate these scores. The response determines and orders the scores, 1)American Basswood – 261; 2) Eastern Hemlock – 291.05; 3) Black Oak – 328.1; and 4) American Beech 370.75 (order may be reversed). The response includes the general formula, Score = c + h + s/4, to determine the score for any tree in the Big Ohio TreeProgram.

3 The response clearly addresses the key aspects of the task; however, it includes minor flaws.For example, the response may:

• Contain an error in one or two of the scores for the four trees, the ranking is correct based on the scores provided and the formula is provided.• Contain the correct scores for each of the four trees listed in the chart, the ranking is incorrect or missing. The formula is provided.• Contain the correct scores for each of the four trees listed in the chart, the ranking is correct. The formula is flawed or missing.• Omit the scores for the four trees; however, ranks the four trees correctly and provides a correct formula.

The formula is flawed or missing.• Contain the correct scores for each of the four trees. The ranking and formula are incorrect or missing.• Contain the correct formula and at least two correct scores, the ranking is incorrect or missing.• Contain an incorrect formula but the scores and ranking are correct based on the formula provided.

Points Student Response

1 The response omits significant aspects of the task. There is evidence of minimal understanding of the concepts involved in the task and/or solution process; however, the response includes significant errors in most of the components of the task.For example, the response may:

• Provide only the formula. The scores for the trees are missing and no ranking is provided.• Contain the correct numerical score for at least two of the four trees. The ranking and formula are incorrect or missing.• Ignore the s/4 in calculations and formula; however, the ranking is correct for the values given.• Contain a correct ranking with missing scores and the formula is missing.

0 The response indicates inadequate understanding of the task and the response does not meet the criteria required to earn one point.For example, the response may:

• Contain the values added without considering the s/4, and no ranking or formula is provided.• Contain an incorrect ranking with only incorrect scores or missing scores.• Include unrelated statements or work.

Points Student Response

2 The focus of the item is to determine the number of miles in one light-year and write this number in scientific notation. The response contains the value of ≈ 5.86 x 1012 with supporting work.

1 The response provides evidence of a partially correct answer and/or solution process. The response shows understanding of some key elements of the task but contains gaps or flaws.For example, the response may:

• Contain the correct value written in scientific notation with incomplete or missing work.• Contain the correct value, but it is not written in correct scientific notation. Supporting work is incomplete or missing.• Provide a correct process for determining the number of miles in one light-year but contains computation errors.• Provide evidence of a partially correct process; (e.g., the conversion process includes the number of minutes in a year, but not the number of seconds.) The value found is written in correct scientific notation.
