Congratulations because you are certainly keeping track of your daughter's development. Nowadays there is a lot of good information on the internet about curricula (as well as bad) you just have to know how to search and be guided by certified and well-supported pages. Homeschooling is wonderful and to balance the socialization skills it is best to have the child participate in some activity, according to their tastes and interests, that allow them to be in contact with other children of their age such as sports, maybe music, dance or painting, a book club or activities like that, that they only develop social skills at school is a myth, there is really more socialization in what is called extracurricular activities because the child has more freedom to express their personality and interact with other children.
