Diane Lopez

This is a very detailed book. It includes an exhaustive list of things to learn each year. However, in one of the chapters in the back, Diane Lopez notes that each family should decide what they want to cover. I.e. you don't need to cover everything in the book, just those things that your family finds relevant.

I have enjoyed using it as a general guide to what my children need to know.

This is a good reference book for those getting started in homeschooling to know what is expected on each grade level.
