                  Look at the following number strip.

                      Left                                                                                     Right

                        1    2    3   4    5    6    7    8   9 10 11 12 13 14 15 16 17 18 19 20

                  Let us count the numbers left to right starting from 4.

                          4            5            6            7            8            9            10

                  Such type of counting is called the forward counting.

                  Now, let us count the numbers right to left starting from 15.

                         15           14           13           12            11           10            9

                  Such type of counting is called the backward counting.

                  1.   Count forward and write the missing numbers.

                       (a)      3     4     5                        9

                       (b)      6     7     8                                                                         20

                       (c)      4     5                                   11                             16

                  2.   Count backward and write the missing numbers.

                       (a)     19                       15                             10

                       (b)                       17                              12

                       (c)     17                             12                                    6
