Scoring Rubric – Individual Assignment
(Exploring the Relationship between Linear Equations and Their Graphs)
General Requirements
Completed
on Time / 5 points is awarded if the assignment is completed on time. If the assignment is late, zero points will be awarded and an additional 10% (of the earned score) per day will be deducted (see below). / 5
Written Communication / 5 points is awarded if the students use correct grammar, punctuation, spelling, and so forth. Complete sentences and clear communication of ideas are also necessary. Finally, the student also needs to use accurate mathematical language. / 5
Neatness/Organization / 5 points is awarded if the student uses the space provided for answering questions, uses Equation Editor as necessary, resizes images appropriately, etc. / 5
Questions on Worksheet
PART I / Question #3 / Full credit (5 points) is awarded if:
  • screen shot is provided;
  • graph reflects the changes described in the directions;
  • at least five graphs (in addition to the y = x line) are sketched;
  • and equations for the lines can be seen.
/ 5
Question #4 / Full credit (15 points) is awarded if:
  • the description accurately addresses how the magnitude of values affects the steepness of the graph;
  • the description accurately addresses differences between positive and negative values;
  • and the description utilizes some type of terminology to accurately describe the characteristics (i.e. slope or steepness, direction of slant, location of the graph relative to the origin, and so forth).
/ 15
Question #5 / Full credit (5 points) is awarded if all 5 values are entered into the appropriate boxes and are correctly calculated. / 5
Question #6 / Full credit (5 points) is awarded if the student identifies that the calculated number is the same as the number that is multiplied and the student identifies the value as the slope of line. / 5
PART II / Question #10 / Full credit (5 points) is awarded if:
  • screen shot is provided;
  • graph reflects the changes described in the directions;
  • at least five graphs (in addition to the y = x line) are sketched;
  • and equations for the lines can be seen.
/ 5
Question #11 / Full credit (15 points) is awarded if:
  • the description accurately addresses how the magnitude of values affects the location of the graph;
  • the description accurately addresses differences between positive and negative values;
  • and the description utilizes some type of terminology to accurately describe the characteristics (i.e. slope or steepness, direction of slant, location of the graph relative to the origin, and so forth).
/ 15
Question #12 / Full credit (5 points) is awarded if the student identifies the value as the point where the line intersects the y-axis (a.k.a. the y-intercept). / 5
PART III / Question #13 / Full credit (5 points) is awarded if the student includes a description of the line’s slope (steepness), direction of slant from left to right, and location on the graph relative to the origin (where the line crosses the y-axis). The student must also describe how the values in the equation “appear” on the graph. / 5
Question #14 / Full credit (5 points) is awarded if the student includes a description of the line’s slope (steepness), direction of slant from left to right, and location on the graph relative to the origin (where the line crosses the y-axis). The student must also describe how the values in the equation “appear” on the graph. / 5
Question #15 / Full credit (20 points) is awarded if the student includes the following steps:
  • using the y-intercept to graph the point where the line crosses the y-axis;
  • using the number in front of x to determine the slope of the line;
  • using the slope to find other points on the line;
  • and using the sign of the number in front of the x to determine the direction that the line slants.
