                  1.  Add the following. One has been done for you.

                       (a)                    6  +  3  +  2  = 11   (b)                            +      +       =

                       (c)                        +      +      =       (d)                        +      +       =

                       (e)                        +      +      =       (f)                        +      +       =

                       (g)                        +      +      =       (h)                        +      +       =

                  2.  Add the following.

                       (a)          1    (b)            3    (c)            4    (d)            7    (e)           3

                                    6                   4                   2                   1                  8

                            +       3           +       7           +       5          +        8          +       2

                  Adding 2-digit And 1-digit numbers

                  There were 12 pencils in a drawer. Hazel placed 7 more pencils in the drawer. How

                  many pencils are there in total?

                  12 is a 2-digit number and 7 is a 1-digit number.

                  To add numbers 12 and 7, we follow these steps.
                      Step 1.  Write the numbers one below  Step 2.  Add the tens.

                                 the other.                                        There is no tens digit in the

                                 First add the ones.                              second number.

                                 2 ones + 7 ones = 9 ones                         So, write 1 in the tens place.
                                 Write 9 in the ones place.                             tens Ones

                                    tens Ones                                             1      2
                                      1      2                                        +          7
                                  +          7                                            1      9
                                             9

                                                                                      Thus, 12 + 7 = 19
