I know money is tight for everyone right now, so I thought I would share some things about which people might not know.
We read Logic by Richard F. Clarke in seventh and eighth grades, but I know some don't start formal logic until a bit later. Having not used Memoria Press, I can't say for certain it's the same, but I did compare the table of contents, and they look quite similar. It's available on archive.org for free. Logic : Clarke, Richard F. (Richard Frederick), 1839-1900 : Free Download, Borrow, and Streaming : Internet Archive
For ninth grade, we plan to use The Truth of Thought by William Poland. It's a book on material logic, and the table on contents lines up quite nicely with Memoria Press's. It is also on archive.org. The Truth Of Thought, Or, Material Logic: A Short Treatise On The Initial Philosophy, The Groundwork Necessary For The Consistent Pursuit Of Knowledge : Poland, William, 1848-1923 : Free Download, Borrow, and Streaming : Internet Archive
Rhetoric is a bit trickier. Aristotle's Rhetoric is available at archive.org. There are several other books on rhetoric at 19th Century Schoolbooks | Digital Pitt
Their rhetoric books are listed under "Elocution" here: 19th Century Schoolbooks | Digital Pitt
Of these works, I'm most interested in Exercises in rhetorical reading by Richard Green Parker.
I plan on working in some of the great speeches we have recordings of, such as I Have a Dream, Ask Not What Your Country Can Do for You But What You Can Do for Your Country, etc.
My rhetoric plans are very much a work-in-progress. Sorry!
Anyway, I know it's not much, but hopefully these books can help someone.
