                  builDiNg 4-Digit Numbers

                  We use groups, like ones, tens, hundreds and thousands to build a 4-digit number.

                                                                                                      Note
                                                                  th H      t    O        Do not add an ‘s’ after the
                     1,000     +    200      +    40     + 2 =     1    2   4    2        name of the place while

                  1,242 is read as 'one thousand two hundred forty-two.'                  reading/writing number names.

                                                                                    th H      t   O
                                3,000                +     400     + 10 + 6 =        3   4    1   6
                  3,416 is read as 'three thousand four hundred sixteen.'

                  Look at the pictorial representations of some more 4-digit numbers.

                                                                                            th H      t   O
                                         6,000                +    100     +     50      =  6    1    5   0
                            Six thousand one hundred fifty

                                                                                                th H     t    O
                                         3,000                +       30       +      8      =  3    0    3   8
                           Three thousand thirty-eight

                                                              Remember
                       We put a zero (0) to fill in places where no place value is mentioned.
                       In a 4-digit number, if there is 0 at the hundreds, tens or ones place, we do not mention it in
                        the number name.
