                  ADDITION FACTS

                  We know that addition means putting together.
                  Madhu had 6 plants in her balcony. She brought 3 more plants. Can you say how

                  many plants are there now?                                                6

                  Here, we need to add the numbers 6 and 3.                            +    3
                  She has 9 plants now.                                                     9

                  The sign of addition is ‘+’ (plus). The numbers to be added are called addends and

                  the answer is called the sum.

                  So,                     6    +    3    =    9           This is an addition fact.

                  Adding 0 to a Number

                  When we add 0 to a number, we get the same
                  number as the answer.                                                Think and Answer

                  (a)  5 + 0 = 5                      (b)     82 + 0 = 82            Each object has a hidden number
                                                                                     under it. Find out the numbers
                            same                                   same              using given addition facts and
                  Adding 1 to a Number                                               complete the last one.

                  When we add 1 to a given number, the sum is                                 +       = 12

                  the number that comes just ‘after’ the given                                +        = 16
                  number.

                  (a)  8 + 1 = 9                      (b)     22 + 1 = 23                     +        = _____
                            after                                  after

                  Order in Addition

                  When we add two numbers in any order, we get the same sum each time.

                  (a)  4 + 5 = 9  or           5 + 4 = 9                (b)  18 + 8 = 26         or      8 + 18 = 26
                                            same                                                      same
