It may seem overwhelming. The number one thing to remember is that you do not need to marry your curriculum! Expect to change things up and be willing to adapt to how well your child is responding to the style of the curriculum. You will want to try different ones, and you should continue to as your kids grow. It doesn't need to break the bank -- use your homeschool funds to get what you want. We also suggest looking at used curriculum options on Amazon. Bridgeway Church in Roseville also hosts a "Homeschool Curriculum Sale" in the summer!
When you enroll in a public homeschool charter, the education specialist that is assigned to you may suggest curriculum that mirrors public school curriculum. You DO NOT need to purchase or use any curriculum that does not reflect your family values. YOU are in control of what you teach your children, and your education specialist is there to make sure your child is meeting state standards and overseeing your funds. If you find you are being railroaded by your education specialist, you may request a new one that better suits your family's homeschool goals.
This depends on what state you live in. For California residents, no religious curriculum can be purchased through your homeschool funds. If you are to purchase curriculum such as The Good and the Beautiful (which would be a great choice!) just know that you'll need to come out of pocket. The only curriculum you can purchase through your CA charter is secular curriculum.
