        Addition on the Number Line
        We can represent numbers on a line. This is known as number line.


        When we add on the number line, we move forward as many steps as the number
        to be added. For example, to add 3 + 2 we start from 0 and jump 3 steps to reach 3.

        Then, we move forward 2 steps more and reach at 5.

                                      3 steps       2 steps

        Let us try one more.

                                              6 steps                   3 steps

                                               6       +     3      =      9





              Fill in the boxes by looking at the number lines.
