Why this is arranged the way it is

Every marketplace for teaching material is built for a classroom teacher. That is not a criticism of them — it is who buys. A classroom teacher has one grade, thirty children of the same age, colleagues down the hall, and an administrator who wants a standard number on the plan. So the shelves are labelled by grade, and that works.

A homeschooling parent has none of that. One child, reading two years ahead and writing a year behind. No colleagues. No administrator. The question is never “what is fourth grade social studies.” It is “what is my nine year old ready for.”

So that is the shelf. Age first. Under every title, in plain words, what your child will be able to do at the end of it and what they need to be able to do to start. Read those two lists and ignore the number, because you are the one who knows.

The standards are here too

Everything carries a documented standards alignment, folded away at the bottom of each product page under a heading about portfolios and filings. If your state asks, it is there and it is real. If it does not, you will never have to look at it.
