SOLVE THE PROBLEMS



                 1   Hisham pasted five number cards at
                     the mathematics corner.


                                    120 748           120 764
                120 732

                            120 740           120 756


                     What is the sixth number card he would paste?

                                                •   Five cards pasted.
                     Understand
                     the problem                   120 732, 120 740, 120 748, 120 756, 120 764
                                                •  What is the sixth number?
                     Plan the strategy          Identify the number pattern.

                                   + 8         + 8        + 8         + 8         + 8

                         120 732 + 8 = 120 740              120 740 + 8 = 120 748


                        Solve            120 764 + 8 =

                                                        1
                                               1 2 0 7 6 4
                                             +            8
                                               1 2 0 7 7 2


                      Check                        6 12
                                         1 2 0 7 7 2
                                       –             8
                                         1 2 0 7 6 4
                                       120 764 + 8 =  120 772


                              The sixth number card he would paste is 120 772.


                                What is the ninth number in the number pattern above?
