b 6.G.A.4 Student response does not include a calculation for the surface area of any of the box designs. Student response includes calculations for at least two of the six possible configurations of the box. The smallest number of these calculations is chosen as the box needing the least amount of cardboard. Student response includes calculations for at least four of the six possible configurations of the box. The smallest number of these calculations is chosen as the box needing the least amount of cardboard. Student calculates the surface area of all six boxes correctly: Student concludes that the minimum surface area is found to be on the box. That box needs the least amount of cardboard. c 6.G.A.2 Student response does not include a length, width, and height of a Crystal Cube. Student response includes length, width, and height dimensions other than Student response includes but is calculated incorrectly. Student correctly calculates the volume of a single Crystal Cube: . 3 6.G.A.4 Student response does not include choice D. Student response includes choice D and two or three other (incorrect) choices. Student response includes choice D and one other (incorrect) choice. Student response is choice D only. 4 6.G.A.4 Student is not able to calculate the surface area of either rectangular prism. Student is able to calculate the surface area, but calculations may have mathematical errors. Student calculates the surface area of one prism correctly but one incorrectly. OR Student calculates both surface areas correctly but does not answer the question. Student finds the surface area of the prisms to be and . The student also states that the prism with dimensions has the larger surface area. 5 a 6.G.A.3 Student does not plot any of the points correctly. Student plots the points backwards. For example, student may have plotted the points , , and . Student plots two of the three points correctly. Student plots all three points correctly.
