Some even numbers such as 6, 8, 24, 28, 32 and 46 are given. If you ask your students to sum any two even numbers given, then in each case they will get an even number. Therefore, by studying the various uses of this type, we can conclude that the sum of any two even numbers is always even. What kind of logic do we observe from the above statement? I. Inductive reasoning II. Deductive Reasoning

Inductive-Deductive Method: It is perhaps the oldest and the most basic method of teaching as well as learning mathematics. All other methods in mathematics utilise this method in different degrees. This is a combination of two methods of induction and deduction
- Inductive Method: Induction is the form of reasoning in which a general law or principle is derived from a study of particular objects or specific processes. For example, on adding 2 and 4, we get 6. Similarly, on adding two even number result is also even.
- It is based on the logic that if something is true for a particular case and is further true for a reasonable adequate number of cases, then it is true for all such cases.
- It helps the learner in developing the ability to reason by observing common elements in the similar instances and arriving at the generalised statement or rule.
- Deductive method: Here the learner proceeds from general to particular, abstract to concrete and formula to examples. A preconstructed formula or principles are told to students and they are asked to solve the different relevant problems with the help of the earlier formula. This method is known as Deductive method of teaching which follows the steps given below for effective teaching:
- Clear recognition of the problem
- Search for a tentative hypothesis
- Formulating of a tentative hypothesis/Choosing the relevant formula for solution.
- Solving the problem.
- Verification of the results
Hence, we conclude that the above statement is about inductive teaching.
