                  1.  Add the following.

                       (a)       T    O         (b)       T    O         (c)       T    O          (d)      T    O

                  2.  Find the sum. (Remember to regroup the ones first).

                        (a)      T    O          (b)      T    O         (c)       T    O         (d)       T    O

                  Swati has 24 beads. She needs 8 more beads to make a necklace. How

                  many beads are used in a necklace?

                  To know the total number of beads, let us find the sum of 24 and 8.

                  First arrange the numbers one below the other according to their

                  place values.

                  Step 1.   Add the ones and regroup.                             Step 2.  Add the tens.
                  4 + 8 = 12 ones = 1 ten 2 ones                                  1 + 2 = 3 tens

                  Write 2 in the ones column and carry over                       Write 3 in the tens column.

                  1 to the tens column.                                                  T    O

                                T    O                                                   1
                                1                                                        2    4
                                2    4                                               +        8
                            +        8                                                   3    2

                                     2

                  Thus, 24 + 8 = 32. So, Swati is using 32 beads in a necklace.
