                                       Learning by Doing

                  Objective: To show the correct time

                  Materials required: Round paper plates (numbers 1 to 12 written
                  on it along the boundary at equal gaps), two cardboard strips of

                  different lengths and glue stick.
                  Note: The length of each strip must be less than the radius of the paper plate.

                  Procedure:

                          Divide the class into groups of two.
                           Each group should have 5 paper plates (numbers 1 to 12 written on it) and

                          5 sets of cardboard strips (each set contains two strips of different lengths).

                          The teacher calls out a time, say 3 o’clock.
                           The group takes one set of cardboard strips and pastes the

                          smaller strip on the paper plate from centre of it pointing to 3                   10 11  12  1  2
                          (as shown)                                                                         9          3

                           Then the group takes the bigger strip and pastes it on the paper                  8  7  6  5  4
                          plate from centre to number 12 (as shown).                                         3 o’clock

                           In the same way, the teacher calls out 4 more time and the group                  or 3:00
                          shows the correct time using paper plates and cardboard strips.
