"Bais Yaakov" means "House of Jacob" and it's a school for girls who follow Orthodox Judaism. It was started a long time ago by a woman named Sarah Schenirer who wanted girls to get a good education while still following their religious beliefs. In Bais Yaakov schools, the girls learn all the regular subjects like math and science, but they also learn about their religion and how to uphold its values. They dress modestly and follow strict rules, but they also have fun and make friends just like kids in any other school. Bais Yaakov schools are important for Orthodox Jewish girls because they provide a way for them to get a good education and stay connected to their faith at the same time.
