There is less peer pressure and more focus on learning, more time to learn subjects in depth, more time for reading. Parents can enjoy watching their kids learn, and they can revive their own joy of learning. You and your children can choose books and activities for learning that excite you. ADHD and learning disabilities often disappear. A relaxed pace means happier kids.
Families can take vacations off-season.
And there are many more reasons. There are as many different methods as there are families. You can purchase a packaged curriculum, design your own or choose not to use a curriculum. You can structure a school-like setting at home, or unschool with a free, unstructured approach. Many homeschoolers practice an eclectic mix, incorporating some texts or workbooks and everyday experiences to create a learning environment unique to their families' needs, style and expectations.
