If you are not interested in teaching at home, you may hire a space on a weekly basis in existing coaching institute, play school, etc. and start teaching. At such places, you would be able to accommodate more students.

Many parents prefer to get their kids taught at home as they want more personalized services. And there are some parents who do not want to travel to pick and drop their kids if the Abacus center is at a distant place. In such cases demand for an Abacus Trainer who can give them personalized service arises. Home tuition for Abacus fetches a good hourly rate as it's not so easily available.
These classes can be held on weekdays also. Since, only one weekly class of 1 hour is given, one can easily teach 15 children on weekdays (if 3 children per day are taught and 5 days in a week are invested). Hence, by giving personalized coaching of Abacus to kids, you may earn handsome money. Abacus class is conducted for 2 hours in centers because the number of students is more but one hour is sufficient if the number of students are 1 to 3 in case of home tuition

Nowadays, many schools have started teaching abacus as a subject. Abacus teacher salary is pretty handsome. So, if you are interested in getting a job, you can easily find a job as an Abacus teacher in any school or educational institute near you.

If you are already running a coaching center, you already have invested in infrastructure and paying monthly fixed expenses, you can add Abacus learning to your curriculum easily without extra expenses. You can utilize your space on Sundays or Saturdays since these classes are conducted only on weekends, it will only add to your income.
