                AdditioN

                Addition is finding the total value of two or more numbers.                      H T O

                • The numbers that are added are called addends.                                 4 0 2
                • The result of addition is called the sum.                                  +   3 4 3         Addends

                Properties of Addition                                                           7 4 5         Sum

                    1.  If we change the order of numbers (addends), the sum does not change.

                        a.       H T O                H T O             b.       Th  H T O               Th  H T O
                                 2 1 4                3 2 5                          3 4 3                1  4 0 2

                              +  3 2 5             +  2 1 4                   +  1   4 0 2            +      3 4 3

                                 5 3 9                5 3 9                      1   7 4 5                1  7 4 5

                                             Same                                                Same

                  2.  If we add zero (0) to any number, the sum is the number itself.

                        a.        H T O                b.        Th   H T O                c.        H T O

                                  3 4 5                           1   4 3 5                                 0
                               +         0      Same           +             0      Same         +   6 5 3

                                  3 4 5                           1   4 3 5                          6 5 3      Same
