I’ve heard that Charlotte Mason didn’t keep an official Scope-and-Sequence in her schools or for her home study programs. She encouraged teachers, parents, tutors, and nannies to come up with their own schedule of study each year to keep the topics fresh for the teacher as well as the student. You often teach best what you’re enthusiastic about because your excitement can be contagious.
But I find that many modern day Charlotte Mason homeschoolers want some guidance about what exactly to study and when.
Numerous people I’ve talked with over the years (including myself) have found the series of Core Knowledge books by E. D. Hirsch, Jr. to be an excellent and highly useful outline of what to study when. The series covers each grade level from Kindergarten through 6th grade. These home educators use the Core Knowledge books as their scope-and-sequence, and then flesh out the various topics with living books and use other Charlotte Mason techniques like narration, short lessons, and nature study to bring the curriculum alive.
Just my humble thoughts — following a quarter century of homeschooling — for what it’s worth.
