Is the word "بسم" (Bism) without the alif correct, and is there a way to teach children the Islamic sciences according to the methodology of the Sunnis and the Community, and to raise them properly, via the internet?

We thank you for your interest in raising children. We advise those interested in Da'wah and Islamic education to create programs that cater to young children. You can refer to distance learning and e-learning websites. Writing "Bismillah" without an alif is correct.
