         Fill in the boxes using multiplication tables.



            7       ×     5     =                                   6       ×     3     =


            2       ×     5     =                                   9       ×     3     =


            4       ×     4     =                                   9       ×     4     =

            8       ×     4     =                                   5       ×     3     =


            5       ×     2     =                                   7       ×     4     =



        Multiplication on the Number Strip


        Let us multiply 3 and 4 (3 times 4) on a number strip

        Start from zero and make 3 jumps of 4 each on the number strip.

        We reach at 12.



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

        So, 3 × 4 = 12
   112   113   114   115   116   117   118   119   120   121   122
