Question: 21. a. Student graphs the points accurately and gives the correct answer: The area of the triangle is 4 square units. The area of the rectangle is 8 square units. b. Student gives the correct answer: A quadrilateral is formed by the two plane shapes. c. Student gives an accurate explanation: Sample explanation: To find the total area of the joined plane shapes, the area of the individual plane shapes would be added together.

d. Student gives an accurate explanation: Sample explanation: Any ordered pair with a negative y coordinate will be below the x axis, and a positive y coordinate will be above the x axis. Any ordered pair with a negative x coordinate will be to the left of the y axis, and a positive x coordinate will be to the right of the y axis. 6.NS.6

23. a. Student gives an accurate and reasonable recommendation: Responses may vary. Sample recommendation: In order for the planners to accurately visualize what they are planning for the park, I would make the following recommendations for their grid map. x axis range: -2½ to 2½ x axis scale: ¼ mile y axis range: -¼ to ¼ y axis scale: 1/32 Check grid map for accuracy with the plan the student developed. b. Student plots points accurately and gives an accurate explanation: I determined where to place the points by confirming the range is equal to the distance given in the prompt. |-2.5| + |2.5| = 5 miles, and |-¼| + |¼| = ½ mile. These match the distances given, so I know that plotting the points (-2½, -¼), (-2½, ¼), (2½, -¼), and (2½, ¼) would mark the corners of the park. c. Student correctly plots and labels points on the grid map: Path placement may vary, however must parallel the x axis. Check grid map. d. Student gives correct equation: |-2¼| + |2¼| = 4½ miles
