|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.2 Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate|
|to the size of the unit chosen. |
|Student Materials: |
|Chart paper |
|Ruler |
|Pencil |
|Teacher Materials: |
|Measuring in Inches and Feet assessment sheets |
|Directions (for teacher to administer assessment task): |
|Teacher may choose whether to assess student individually, in small groups, or as a whole class. |
|Hand out Measuring in Inches and Feet assessment sheets (one per student) |
|Tell students “You will measure the length of a chart paper using your ruler. Write how many inches long the chart paper is. Then, you will measure |
|the same chart paper a second time and write how many feet long it is.” |
|Read part “C” aloud. |
|Tell students “Finally you will write why the measurements are different. Don’t forget to include why there was more of one unit than the other.” |
|Have students work independently on task |

|feet) to measure something. |
