                    Let us try these:

                    What comes after 9? __________                      What comes after 99? __________

                    What comes next to the greatest 3-digit number? __________

                    What is the smallest 3-digit number? __________

                    Can you think of the smallest 4-digit number? __________

                                           999 = 900 + 90 + 9 and 999 + 1 = 900 + 90 + 9 + 1

                                                              +                   +       +     =

                                            900               +        90         + 9     + 1   =     1000

                    Thus, 999 + 1 = 1000.

                    1000 is a 4-digit number. It is read as one thousand.                     10 hundreds make
                                                                                                 1 thousand.
                    1000 is the smallest 4-digit number.

                    Rashi and Mahi were doing their work. They were writing
                    the numeral for the number name given as: “One thousand one”

                    Rashi wrote 10001.

                    Mahi wrote 1001.

                    They started arguing over who was right.
                    Rashi's mother: What happened why you girls are arguing?

                    Rashi: Mother, look at our answers and let us know who is right.

                    Mother looked at both the answers and said Mahi was right.

                    rashi: Why?

                    Mother: What comes after 10, Rashi?

                    Rashi: Eleven

                    Mother: Please write it.
                    Rashi: 11

                    Mother: What comes after 100?

                    Rashi: One hundred one, 101.

                                                                                                                  9
                                                                                                     Numbers
