I think we're going to wait to do formal Kindergarten with The Marvelous Flying Marco, until this upcoming year. He'll be 6, but not until the summer. He's technically "doing" kindergarten now, but with his special needs, this year has been spent almost entirely on finishing short tasks, finding a reward system that works for more than a minute, and moving from whatever he is rigidly focused on and into a mom-directed activity for even a very short period of time.
We are making progress there, but almost no actual academics have taken place. I'm not super concerned, because he's known his letters (and their sounds), recognizes his numbers through I-don't-even-know (numbers are his "thing"), shows an understanding of the concept of addition/subtraction in play, and enjoys read alouds.
So, we'll take another stab at formal K this upcoming year.
Memoria Press copybooks
CLE Math 1 *or* Miquon (not sure yet about this -- older kiddo uses Miquon, but when I think about the time spent on it, and the time I have available, the idea doing it with another kid, since DS8 is still using it, makes me want to cry)
He can tag along with DS8 for literature and enrichment subjects (we use Memoria Press for literature/enrichment and crafts; TAN's Story of Civ 2 for classical studies).
All of the kids do "Morning Meeting" together, which is comprised of individual recitations (age appropriate for each kid); picture study, religion, great words studies, and Latin.
