Illuminations: Going Places

# Going Places

## Measuring with Teacher’s Feet

 In this lesson, students use nonstandard units to measure the distance between objects found in their classroom. They create a nonstandard unit by using an outline of the teacher’s foot and cutting around it to use as a “measurer.” Students generate a list of four or five objects in the classroom from which they will measure the distance to their workspace.

### Learning Objectives

 Students will: recognize and use the attributes of length measure using nonstandard units repeat a single unit to measure something longer than the unit

### Materials

 Construction paper or lightweight posterboard Chart paper Crayons or markers Scissors Getting There With Teacher's Feet Activity Sheet Sample Foot Measurement

### Instructional Plan

 Trace an outline of the teacher’s foot on construction paper and cut it out. Tell the students that this is the tool you will use to measure distances in the classroom. Have students identify four or five objects in the room and use the cutout to measure the distance from where you stand to those locations. Record on a chart the location and the number of “feet” required for reaching them. Recording this information on a chart allows student to refer to it during the lesson. A Sample Foot Measurement is provided for your use. These could be used to create an overhead transparency to demonstrate how to place the foot end-to-end in order to measure longer distances. Pair students and have them use multiple cutouts of your foot to measures the distances from their workplace to the identified objects. Using a lightweight poster board makes the foot “measurers” more durable. You should provide plenty of copies of the cutout of your foot or have students cut multiple copies so that they may practice measuring with multiple units before using only one unit.     Have each student measure and record the distance from his or her “workspace or home base” to the objects you measured. (A management strategy could be to have pairs of students record for each other. While one student measures, the other might record.) Distribute the Getting There With Teacher’s Foot Activity Sheet to students so they can draw pictures of the destination objects and to write the number of “feet” required to reach them. Set a timer or tell the students how long they will have to complete the task. At the appointed time, have students gather with pairs seated beside each other. Have each set of students share the result of their measurement. Discuss the differences in measures and how they happen.

### Questions for Students

 When you measured the distance between our workspace and the objects, what did you notice? [Student responses may vary, but they may include: the greater the distance between the workspace and the object, the more feet needed.] Which object required the most number of feet? The least? [Student responses will depend upon the distances involved in today's measurement activity.]

### Assessment Options

 You may choose to use the Class Notes recording sheet to document student progress in this unit.

### Teacher Reflection

 Were the learning expectations and pacing of this lesson appropriate for your students? How could the lesson be changed to achieve the learning objectives? What prerequisite activities should students have prior to this lesson? What remediation activities would help students learn the objectives of this lesson? What experiences or activities would challenge competent students?

### NCTM Standards and Expectations

 Geometry Pre-K-2Describe, name, and interpret direction and distance in navigating space and apply ideas about direction and distance. Measurement Pre-K-2Recognize the attributes of length, volume, weight, area, and time. Understand how to measure using nonstandard and standard units. Measure with multiple copies of units of the same size, such as paper clips laid end to end.
