                     Observe the  garden on the  previous  page  and  answer the  following

                     questions.

                       1.  Anu watered the rose and dahlia plants.
                             How many plants did she water?                               +               =

                            plants
                       2.  Aditya watered the marigold and sunflower plants.

                            How many  plants  did  he water?                              +              =
                            plants

                       3.  Who watered more plants?

                            How many more?                        -              =             plants
                       4.  11 roses were blooming. But 4 fell down.

                            How many roses are left on the plants?                           -             =

                  Addition

                  Adding a 2-digit and a 1-digit number

                  Example 1. Add 35 and 3.

                  Solution. We can use a number strip to find the answer.

                     31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

                  Find 35 on the number strip. Move forward 3 places, you reach 38.

                  Thus,  35 + 3 = 38.
                  We can also use vertical addition to find the answer.

                  Step 1. Add the ones.                                 Step 2. Add the tens.

                                   T O                                                  T O

                                   3 5                                                  3 5

                               +       3                                            +        3

                                       8              +                                 3 8

                  Thus, 35 + 3 = 38.
