                 Topic- Subtraction


                 Learning Objective:
                 Students will be able to:
                    •  Use real life objects to subtract the numbers.




                 Discussion:


                    •  Giving a few erasers to the students.
                    •  Asking them to count erasers.
                    •  Instructing them to take away some erasers.

                    •  Asking them to count the erasers again.
                    •  Explaining that Subtraction is the process to find out the

                        difference between two numbers.
                    •  Introducing the ‘-’ sign to reinforce the concept of

                        subtraction.
                    •  For example- 3 erasers+2 erasers=5 erasers.

                 Questions(oral):
                    •  Subtract 4 plums from 9 plums and find out how many
                        apples left.

                    •  10-5=?
                    •  6-2=?
