One option is to choose a company and teach all subjects from that company's curriculum. Many companies offer curriculum packages by grade. These packages include these subjects: math, language arts, science, social studies, health, music, art, and, in some cases, religious instruction. This is an option which is much less labor intensive than others. Parents can simply follow the scripted lessons and instructions which are provided with each subject.
Most states have virtual schooling options. These virtual schools are not considered by many to be true homeschooling. Students are getting an education in their home; however, they are technically enrolled in a public school and completing their assigned coursework at home. The public school district the student is enrolled in provides each student with the curriculum and materials they need. Typically this includes a computer. Many parents like this option not just because of the comfort which comes from being overseen by a certified teacher, but also because there are no costs beyond the normal supplies that any public school student would need.
Unschooling can be nebulous, difficult to define. According to Mary Griffith, "Unschooling uses children's natural curiosity to propel them into a world of learning." Unschooling allows the student's interests to lead education. Often unschooling families shun formal curriculum and textbooks, opting instead for lessons learned from life. In a state with more stringent regulation of home schooling, unschooling is difficult if not impossible. Parents who choose unschooling work hard to mold their children into self-motivated learners.
Many homeschooling parents choose a combination approach, picking and choosing a little bit from each of the above listed types. Math curriculum may come from one company and language arts from another. Students may learn some subjects virtually, especially if the parent feels she does not have the expertise to teach that subject area. Even other subjects, like science and social studies, may be taught with an unschooling approach. Parents typically choose this method when they find that one type alone does not meet their child's needs.
