TITLE:  Step Lively! 
 

CONTENT  AREAS:   
 Mathematics

GRADE  LEVEL:   
 1-4

MATERIALS   NEEDED:   
 None

KEY   CONCEPTS:
 * student gains experience with linear measurements

* student gains experience with transferability

EALR'S (Make the connections clear and specific):   
 1.2 understand and apply concepts and procedures from measurements attributes and dimensions

GOALS:

 The student will gain experience with linear measurements (meters) and recognize that measurements can be approximate, or more precise.    
 

OBJECTIVES:   
 Following a repeated experience in pacing off 10 meters, the student will use their paces to measure at least three distance between places on campus.

PROCEDURES:  (Label each step in the process:  Activating Prior Knowledge, Disequilibration, Elaboration, Crystallization)

• Introduction/Preassessment

     When I count to three everyone close their eyes and by holding your hands apart in front of you show me how far one meter is. One, Two, Three. 
     Open your eyes. Look around.  Now look at this meter stick.  How close were you?   

• Activity

     Over here, I have measured off 10 meters.  You are to pace the distance off to see how many paces equal 10 meters.  Everyone needs to repeat the pace-off three times to be sure you are accurate.  Get together with a partner to help you keep track.  You can use an average of the number of paces or the most often occurring number.  Record your paces on the chart.

Next, with your partner, find the distances between two places on campus.  You need to go in a straight line.  (This is a linear measurement.)  Record your paces on the chart and calculate the approximate distance between places.  Report back here in 15 minutes.
    
    

• Closure

     (After all the students get back.)  Tell me some of the distances you measured.  How many paces did you walk?  How many meters is that?  (Record on board several measurements)

Does anyone have any comments on the process?
    
 

POST-ASSESSMENT    Everyone turn in their record sheet to me when you go.
