The Charlotte Mason style of homeschooling is really a method. She believed in education the whole child not just the mind. Rather than write a bunch on this I'm going to give you this link (CLICK HERE) Sonya Schaeffer from Simply Charlotte Mason does an excellent job explaining the Charlotte Mason video and has a video to explain more. It's a fabulous introduction to what a Charlotte Mason education is - so read and watch.
There are many curriculums that claim to be Charlotte Mason inspired however, very few are truly CM. I would highly encourage you if you are just looking into Charlotte Mason to dig into information that will give you a true (or "whole hog" as they call it in CM world) reflection of a Charlotte Mason philosophy. Many of these "inspired" CM curriculums say things that are not true to CM and their curriculum would not hold up to the standard of CM.
