This is a method of homeschooling founded by Charlotte Mason, a teacher in Victorian England, who advocated educating children by offering them a gentle, full, life with daily observation of nature, daily exposure to fine music and art -– both observed and practiced; the use of living books, as opposed to textbooks, which do not allow the characters to come to life, and other high-quality activities that provide the child with an appreciation for the life that is all around him/her.
