                    Solve the following addition sum and colour their solution in the given grid.

                    When the solution of two sums is same then call out ‘Bingo’ loudly.

                  Addition of 3-digit numBers without regrouping

                  Rinki donates `729 and Pinki donates `210 monthly to the
                  needy people.

                  Pinki: Rinki, can you say how much do we donate together?
                  rinki: To know our total donation, we have to add 729 + 210.

                  Pinki: Okay, let us add these numbers using a place value table.

                  First write the numbers in columns and then add.

                   Step 1. Add the ones.              Step 2. Add the tens.              Step 3. Add the hundreds.
                      9 + 0 = 9 ones                     2 + 1 = 3 tens                     7 + 2 = 9 hundreds

                               H    t    O                        H    t    O                        H    t    O
                               7    2    9                        7    2    9                        7    2    9
                           +   2    1    0                    +   2    1    0                    +   2    1    0
                                         9                             3    9                        9    3    9

                   Thus, 729 + 210 = 939

                   That is, their total monthly donation is `939.
