                                               sitting in first tree, 35 birds in the second tree and

                                               40 in the third tree, how many birds are sitting in
                                               the three trees?                                                +

                                               Answer: ________________________________

                          Mental Maths
                     1.  Study the addition patterns and complete the following table:

                         Since     3 + 3 =  6     Since    5 + 2 =  7     Since     7 + 8 =  15 Since       9 + 9 =  18

                         So,      13 + 3 =  16 So,        35 + 2 =  37 So,        27 + 8 =  35 So,         19 + 9 =  28

                                  23 + 3 =  26            45 + 2 =  47            47 + 8 =  __             49 + 9 =  __
                                  33 + 3 =  36            55 + 2 =  __            67 + 8 =  __             59 + 9 =  __

                                  53 + 3 =  56            75 + 2 =  __            87 + 8 =  __             89 + 9 =  __

                     2.  Nine  squares  have shown  in  this  figure which  are arranged
                         diagonally  with  number  9  at  the  centre.  Fill  in  the  remaining
                         squares with numbers from 1 to 8 in such a way that the sum of                        9
                         both the numbers in the squares in each side should be equal to                   2

                         9. One has been done for you.                                                 7
