                                       Learning by Doing

                  Objective: To learn addition of 4-digit numbers in a play-way method.

                  Materials required: Paper and pencil
                  Procedure:

                          The teacher can take children to the school parking area and tell them

                          to note down the 4-digit vehicle numbers of any four vehicles.  Or she/
                          he can ask them in advance to note down the vehicle numbers while                        xy* m7234
                          they are coming to the school.

                          Then children will be grouped to work in pairs.

                          Each child will make four slips and write his numbers. Next each child will take out a
                          slip and show the number to each other. Then, they will find the sum of the two 4-digit

                          numbers with the condition that he/she will write his/her own number on the top row.

                         For example,  Child A:  2158                Child B:  4693
                          So,                        2158                     4693

                                                    + 4693                   + 2158

                                                     6851                             6851
                          Check the working of each other and discuss the answers obtained.

                          Note that the answer should be a 4-digit number. If the answer is a 5-digit number,
                          it will be ignored and new pair of numbers will be tried.

                     Add all the numbers of the middle circle with the number in the centre and write the

                     answers in the places given in the outer circle.
