CCSS Mathematics Assessment Task

Grade Level: 2
Mathematics Domain and Cluster:
Domain: Measurement and Data
Cluster: Measure and estimate lengths in standard units
Common Core standard(s) being assessed (if the task is intended to assess only one part of the standard, underline that part of the standard):
2.MD.4: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
2.MD.1: Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
Student Materials:
·  How Much Longer? Assessment #1
·  Rulers
Teacher Materials:
·  Copies of How Much Longer? Assessment #1
Directions (for teacher to administer assessment task):
This assessment can be given as a whole group or as a small group. If given as a small group, the teacher is able to directly observe if each child is able to measure correctly and accurately.
1. Read through the assessment task.
2. Students to work independently, even though they are in small groups.
3. Collect when completed.
Prompt:
See attachment.
Correct or Model Answer:
Black Ant traveled 4 inches.
Red Ant traveled 6 inches.
The Red Ant traveled 2 more inches than the Black Ant.
Scoring Guide/Rubric (a score should be awarded for each criterion below)
Criteria (CCSS code) / 0 points / 1 Point / 2 Point
Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. (2.MD.4) / Student is unable to determine how much longer one object is than another. / Student is somewhat able to determine how much longer one object is than another. / Student is able to determine how much longer one object is than another.
Measure the length of an object by selecting and using appropriate tools (2.MD.1) / Student is unable to select an appropriate tool and is unable to measure the objects. / Student is able to select an appropriate tool but needs assistance when measuring the objects. / Student is able to select an appropriate tool and accurately measures objects.
