As a homeschooling parent, we all know the costs that go along with this decision. This is most likely why some people are looking for free homeschool curriculum material. If you look long and hard on the internet, you will most likely come across a few websites out there with some printouts and sheets you can work on. You might even find some sites that tell you what you should be teaching. But, is it really worth all of the hassles of doing this?
I would just recommend buying the entire package of what your child should be learning at one time. This will free up so much of your time. Not only will you have everything your kid needs, but you will have everything you need as well. Your teacher's guides come with packages like this. And, you can ensure every subject actually gets taught. There are some sites out there where you can just buy the entire Grade 3 curriculum at one shot. It will come with all of the subjects (probably like 5 subjects). This would include the books, workbooks, and teacher's guides. It will make things so much easier for you.
If you are really just not wanting to buy anything, then your next best bet is to find some teachers in the school system. They always have extra materials, and maybe even last year's curriculum handy. Most of the time they end up throwing this stuff away. You could ask them if you could have any of the extra materials they have. This might help you save some money. But it will not help you save time.
You will now need to piece all of this stuff together and try to figure out how to teach it all. It gets frustrating after a while. This is why many homeschooling parents now are just buying the entire package of books. They figure it was just easier to buy the homeschool books instead of looking for free homeschool curriculum material. But, the choice is yours.
