Grade 3 Unit 12 Constructed Response Data and Graphing Description Task
Common Core State Standard for Mathematical Content (MC)
Standards for Mathematical Practice (MP)
1. Scaled Picture Graphs
3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve oneand two-step “how many more” and “how many less” problems using information presented in scaled bar graphs.
MP.1 MP.2 MP.3 MP.6 MP.7 MP.8
2. Scaled Bar Graphs
3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve oneand two-step “how many more” and “how many less” problems using information presented in scaled bar graphs.
MP.1 MP.2 MP.3 MP.6 MP.7 MP.8
3. Measuring and Plotting Length on Line Plot Graphs
3.MD.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units – whole numbers, halves, or quarters.
MP.1 MP.2 MP.6 MP.7 MP.8
Note to Teacher: The following scoring rubric should be used as a guide to determine points given to students for each question answered. Students are required to show the process through which they arrived at their answers for every question involving problem solving. For questions involving a written answer, full points should be given to answers that are written in complete sentences which address each component of the questions being asked.

Scoring Rubric Question 1. a. Student gives the correct answer. 15 more students chose the Third Grade Play. b. Student gives the correct answer. 90 students did not choose the Pancake Breakfast. 2. a. Student draws an accurate scaled picture graph.
b. Student gives the correct answer. 40 fewer students c. Student gives the correct answer. 100 students 3. a. Student gives the correct answer and an accurate explanation. Wording may vary. Sample explanation: Marisol’s scaled picture graph does not correctly represent the data. She used a picture for each response, but we know the pictures are scaled to represent 2 responses. She should have drawn 3 triangles for reading, 2 triangles for social studies, 5 triangles for math, 1 triangle for science, and 2 triangles for P.E. b. Student draws an accurate scaled picture graph.

4. a. Student gives the correct answer. 12 students b. Student gives the correct answer. 2 more students 5. a. Student draws an accurate scaled bar graph.
b. Student gives a correct answer. Answers may vary. Either Mr. Lograrian and Mrs. Valentine OR Mr. Lograrian and Miss Stephani. c. Student gives the correct answer. 28 students 6. a. Student gives an accurate explanation. Wording may vary. Sample response: Yes, Darcy’s and Thao’s graphs both correctly display the data. Darcy’s scaled bar graph is vertical and Thao’s is horizontal, but they both list the teachers and the same number of students who are returning to the school for fourth grade. Darcy used a scale with a bar representing every two students and Thao used a scale with a bar representing every four students, but both display the correct number of students.
