Measuring in Inches and Feet

|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.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 |

|Prompt: |

|See attachment. |

|Correct or Model Answer: |

|Answer may look similar to this. |

|The chart paper is ________ inches long. |

| |

|The chart paper is ________ feet long. |

| |

|Measuring in inches is different than measuring in feet because an inch is smaller than a foot. Since an inch is smaller, it takes more inches (than |

|feet) to measure something. |
