Nowadays it is difficult to get a teaching job without doing B.Ed. You can try to get a temporary job in a private school or coaching centre but for a regular job the B.Ed. degree is required.
For Govt schools one has to, in addition to B.Ed., qualify in 'Teacher Eligibility Test' conducted by the respective state governments or 'Central Teacher Eligibility Test' conducted for central government schools.
However as you have already acquired a M.A. degree, there is another route open for you and that is National Eligibility Test (NET) and if you qualify in that you can apply against the lecturer vacancies advertised by so many institutions and colleges in our country.
If you have interest in research and can complete PhD then after that you can directly apply for lectureship in universities and colleges and in that case you need not to go through NET route.
So you have to wait till you complete B.Ed. but you can try for a temporary teaching job as a part time in some private school or tuition centre and earn some money on the sides of your B.Ed.
Please do not hesitate to join a small teaching job as it will give you experience which is the most valuable thing in this line.
Here, I will take liberty to quote my own example as I had worked as teacher for a few years before shifting to other job. After doing my M.Sc., I was desperately searching for a job but due to the tough job condition at that time (it was the year 1972) I was roaming here and there. Somehow, I got a temporary teaching job. When I started preparing for the teaching I found that there are many things which I have to fully understand and learn before I teach it to the students. Within one year my knowledge and experience was much more than when I joined there as a fresh teacher. Believe me, this tremendously helped me in building my confidence and knowledge and within 2-3 years I left that job and switched to a better one.
So, it is only when you do things by yourself, you know where you stand and then only learn and get experience.
So go ahead and all the best.
Knowledge is power.
