                                       Learning by Doing

                  Objective: To estimate the length, weight and capacity and compare.
                  Materials Required:

                  For length: A paint-brush, water bottle or any other things

                  For weight: A toothpaste packet, soap or any other things on which weights are

                  mentioned
                  For capacity: A cold-drink bottle/can, a juice packet or any other things on which

                  capacity is mentioned
                  Procedure:

                          The students perform the activity in pairs.

                          One member guesses the length of a paint-brush and write its estimated

                          length.
                          The other member measures the actual length of the paint-brush using a

                          centimetre ruler and write it.

                          Now, the first member takes a toothpaste packet in his/her hand and guesses
                          its weight. He/she write its estimated weight.

                          The other member reads the weight mentioned on the toothpaste packet

                          and write it.
                          Now, the first member takes a soft-drink bottle and write its estimated capacity.

                          The other member reads the capacity of the soft-drink bottle mentioned  on

                          it and write it.
                          Similarly, the length, weight and capacity of other objects can be estimated

                          and compared with actual measurement.
