              Complete the following subtractions by counting backwards. One has been done
              for you.


              1.  11 – 5 =  6          11     10     9      8     7      6

                      Challenge Question                                                                     Critical Thinking

                  Ravi had 10 gas balloons. Some of them floated away, and now only 3 balloons
                  are left with him. How many balloons floated away?


              Subtraction on a number Line


              We can subtract by counting backwards on the number line. Let us subtract 6 from
              14. We start with the bigger number 14 and jump 6 steps backwards. We reach 8.


                                                           6    5   4    3   2    1


                     0 1      2   3    4   5    6   7    8   9   10  11   12  13   14  15   16  17   18  19   20
                                                        Thus, 14 – 6 = 8

                 Kunal bought a bunch of 18 bananas. When he was returning home,
                 a  baby  monkey  caught  his  feet  asking  for  food.  Kunal  gave  him  6  bananas.  The  baby
                 monkey ran away happily with the bananas.

                 1.  How many bananas were left with Kunal? 2. Do you like giving food to the hungry?
