3 Rubric Part A Score Description 2 Student response includes the following 2 elements. Reasoning component = 1 point o The student explains or shows that Jack correctly rounded to the nearest ones place. Reasoning component = 1 point o The student explains or shows that Courtney correctly rounded to the nearest tens place. Sample Student Response: Jack correctly rounded the precipitation to the nearest ones place. This means that Cedar Falls, with a precipitation of 15.68, and River Valley, with a precipitation of 16.43, would both round to 16. Courtney correctly rounded the precipitations to the nearest ten. All four towns would round to Student response includes 1 of the above elements. 0 Student response is incorrect or irrelevant. Rubric Part B Score Description 2 Student response includes the following 2 elements. Computation component = 1 point o The student provides a response that a precipitation amount can be greater than (the amount must be greater than the precipitation amount for Hill City) and less than Reasoning component = 1 point o The student justifies that the conclusion is incorrect. Sample Student Response: The amount for Hill City rounded to the nearest tenth is There are numbers above 21.5 that would also round to The amount should be greater than and less than Student response includes 1 of the above elements. 0 Student response is incorrect or irrelevant.

It includes each of the two required elements: The student explains or shows that Jack correctly rounded to the nearest ones place (Jack and Courtney could both be correct as they both would have rounded to different places. If Jack rounded to the nearest whole number, Cedar Falls and River Valley would both have an annual rainfall of 16in.). The student explains or shows that Courtney correctly rounded to the nearest tens place (If Courtney had rounded to the nearest ten digit, all the towns would have an annual amount rainfall of 20in. This proves that Jack and Courtney could both be correct). Part B: Score Point 2 This response receives full credit. It includes each of the two required elements: The student provides a response that precipitation amount can be greater than and less than (The annual precipitation for Plainville must be greater than and less than 21.55). The student justifies that the conclusion is incorrect (Jack and Courtney s conclusion is incorrect. If we round to the nearest tenths place, we would get If we took 21.54, which is more than 21.50, we would also get 21.5, if we rounded to the tenths place.

Cedar Falls and River Valley both rounded up and down 16 which is why he could only get two of the same number). The student explains or shows that Courtney correctly rounded to the nearest tens place (Courtney rounded it to the nearest tens place which is why he got all of them to the same number. They all rounded up or down to 20). Part B: Score Point 2 This response receives full credit. It includes each of the two required elements: The student provides a response that precipitation amount can be greater than and less than (It has to be more than and less than 21.55).
