The student may not score more than 3 points if the student does not correctly identify the units as cubic centimeters (cm3). 4 5.MD.5 The student is neither able to calculate the height of the prism nor able to draw and label a model. The student is able to either find the missing height or draws an unlabeled model. The student draws a labeled model showing 60 in2, and some inches high, but makes a calculation error when finding the height of the prism. The student clearly does the following: Draws a rectangular prism as a model. Labels the model, including inches for height and inches squared for the base. Calculates the height of the prism as 14 in. 5 5.MD.5c The student is able to calculate the volume of one part of the figure but is unable to explain the reasoning used. The student explains the reasoning used but makes more than one calculation error. The student explains the reasoning used but makes one calculation error. The student may not score more than 3 points if the student does not correctly identify the units as cubic inches (in3). The student does the following: Correctly calculates the volume of the prism as 4,080 in3. Clearly explains the reasoning used. A Progression Toward Mastery 6 5.MD.5b The student is unable to correctly answer any part of the task. The student correctly answers either Part (a) or Part (b), but does not explain the reasoning used. The student calculates either Part (a) or Part (b) correctly and explains the reasoning used. The student may not score more than 3 points if the student does not correctly identify the units as cubic centimeters (cm3). The student correctly does the following: a. Calculates 9,000 cm3 and clearly explains the reasoning used. b. Calculates 18 cm and shows correct work and reasoning.
