I myself was homeschooled as I lived in a small town and the local cheder closed down. I did this for a few years until we were able to move to a larger city. I have experience and have a few points that I would like to bring up.
1) For Lemudei Kodesh we went to the Rav who used to run the day school and he tutored us along with a few families that also were homeschooling. We all did the Lemudei kodesh together in the Rav’s office and side room of the shul. He hired all the teachers if he was unable to do it. Who will be teaching your children Lemudei Kodesh?
2)The Secular studies aspect- i am not sure about where you live, but where I lived there is something called truency. You have to be enrolled in a school so the public school system had a homeschooling program. All you did was come in to an officec once a week and turn in your completed homework that they assigned the week before. We worked at my level, which was good. By the time I entered a real school, I was ahead in many areas. You need to find out if your city has this option.
3)Skill wise- I said I was ahead in some areas, but the problem was that I was behind in others. See what age you want your children to join a regular school and see their level and gauge if you can do it. Problem: some things you cant teach your children (science labs) and your children will be behind in it.
4)Socially- I did not have many friends homeschooling, as there were few frum kids my age. I knew one girl my age, one a year younger who moved away, and I had my younger sister who was two years younger then I was. Certain social skills like being in a classroom, being with other teachers besides “mommy”, having to follow strict schedules and rules…. can only be learned in a classroom with other kids. Also group work can only be done with a group! Also, I did not have test-taking skills that I needed, so it was hard for the new school to realize that I knew the math and they put me in the low class (remedial) instead of the honors class (the school split math when I entered the school.
Hatzlacha in making this major decision! There are benefits to both sides, but I mainly addressed the issues as you seem to have some positives in mind that you are contemplating this idea.
5) as the mother, you need to be prepared to teach the information or hire someone to teach it. You need to know the material and be able to explain it in a way they can understand. I was more independent and would do my work on my own and read the chapters in the history book by myself and then later on ask my mother a few questions I had. It helped me with independent learning skills that many kids who go to regular school do not have, as I found out later.
There were many benefits and I dont want to scare you off from homeschooling. I was ahead in a few areas. Also, scheduling was easy- I did extra work in december and during the goyish holidays and I got sukkos and yomim tovim off. I had to do a lot more work in the weeks prior to the yom tov, but i got chol hamoed off. Also, if we had a family simcha, I just did extra work the week before I left (we had special arrangements made with the office). Also, if we went on a family trip to visit my family for a long trip, I would visit a museum or two and write a “report” (depending on the age, it meant different things) on something I learned there. And I would read a few books on the plane or in the car and write book reports ect. I also was able to study what I was most interested in. They would give you a few titles of age-appropriate books and we would pick the one I liked the best. There was a lot more leway with homeschooling. They would give you enough work for the week and I would do it all on monday and tuesday (work really hard those days) and have the rest of the week off if it was rosh hashana later in the week, or we just had plans to do something then.
