          In early classes, handspan, footspan, cubit and pace   You have already observed that two
          are introduced to kids as they are easy to grasp.       different persons may give different
                                                                  measurements for the same length.



























                  They are informal units of measurement.                     You are right, papa. But, is it even
                      They vary from person to person.                      possible to measure things accurately?


            Yes, It is. With standard units of                                       Thanks a lot, papa. But from
          measurement, we can do it perfectly.                                          where we can learn it?





























                            Whether it is length, weight or       Easy, go to the next
                            capacity. It works everywhere.       pages of this chapter.


                           Separate the students into two groups. Place some items on a table that can be used to teach
                           children how to measure. Now, select one group to be measured using informal units such as
                           handspan and cubit. Give the class a quick overview of the standard units of measurement. Call
                           out the other group and have them use the standard unit to measure the same objects. Encourage
                           the students to take notes on their observations.
