2  The following are four number cards.


                                540 500                                      541 250
                                              538 900        536 500







                     a  Which number has a smaller value, 536 500 or 538 900?

                          hundred           ten
                         thousands thousands          thousands hundreds tens ones
                              5              3              6            5         0       0
                              5              3              8            9         0       0



                                same digits                Compare the thousands digits.

                        Value of digit 6 is 6 000. Value of digit 8 is       .
                              is less than       .


                         536 500 is smaller than 538 900.


                      b  Arrange all four numbers above in descending order.


                          Let’s use a number line.



                               536 500                   538 900         540 500        541 250



                          536 000  537 000  538 000  539 000  540 000  541 000  542 000


                             Descending order        541 250, 540 500, 538 900, 536 500



                               • Ascending order - numbers arranged from the
                                 smallest to the largest value.
                               • Descending order - numbers arranged from
                                 the largest to the smallest value.




              8                1.1.2   • Stress that any number sequence in ascending or descending order
                              (iii), (iv)
                                       may not necessarily form a pattern.
