Every home school seems to use a different curriculum. There are so many types to choose from. You can choose a textbook type curriculum or a child directed curriculum. There are countless types that fit between these two categories. I use a few different types. I have some workbooks for math, grammar and spelling. I have an all-inclusive curriculum for everything else. This one curriculum, My Father's World, allows me to school all of my kids at the same time. All 5 kids listen to the books and lessons we read aloud. All 5 are therefore studying the same thing in history, science, art, music, and Bible. This is one of the most helpful things about our home school curriculum. I am schooling 4 different ages of children and I would have a very difficult time schooling them if I didn't have just such a curriculum. This works well for me, but would it work for everyone? Of course not! Each child is unique in their learning style and each parent is unique in their teaching style. Some need more structure, others need little structure. Some need lectures, some need independent work. Not only are the styles unique for each person involved, but they can change from year to year. I use what I am because it suits us this year. Will I continue doing everything the same next year? Not likely. I will more likely tweak some details of our schooling. I may hear about some awesome curriculum between now and then that I want to try. That's not important. What matters most is that what we use works for our family right now.
When I first began home schooling I was told, "Pick something for this year and commit to it." If it works, that's great. If not, change it the next year. I am into my third year of this and I have not had two years the same yet. I have taught using different curriculum and I have taught different ages of children. If you are new to home schooling, pick something and start in. Don't feel like you'll be stuck with your decision forever. Just start.
