I came across this list of free Saxon ‘Samplers’ (some more than 100 page of text, ideas, and problems!) for math programs K-HS, phonics, grammar, etc…all free to download.
I think they could be quite useful as supplementation to other programs, give you a feel for what the programs are like, or even just give additional ideas and checklists…

Oh I had forgotten about these, yes a very good checklist and comparison. It’s actually enough information for a clever person to create their own program for. But I do like the way Saxon script it all for you, they ensure the right vocabulary is used and build on over time.
We enjoy using the 5/4 Saxon. Its systematic nature is good for older kids.
The k to 3 has very advanced use of calendars and graphs. As well as a very solid grouding in patterns and time.
