                           Practice time 5b

                  Complete the following subtractions by counting backward.

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

                  2.  18 – 9 =

                  3.  17 – 5 =

                  4.  19 – 8 =

                  5.  15 – 5 =

                  6.  14 – 6 =

                  7.  16 – 7 =

                  Subtraction on a number Line

                  We can subtract by counting backward on the number line.

                  Let us subtract 6 from 14. We start  with the bigger number 14 and jump backward

                  6 steps. 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?
