Unschoolers don't bother with lesson plans, curriculum, assignments, tests, grades, workbooks, homework, or other academic requirements because we have discovered that children who grow up in a stimulating and enriched environment, surrounded by family and friends who are generally interested and interesting, will learn all kinds of things and repeatedly surprise us with what they know. If children are supported in following their own inclinations, they will build strengths upon strengths and excel in their own ways whether those are academic, artistic, athletic, interpersonal, or whichever direction that particular child develops.
(If September 2014 isn't gone when you read this,
you might have a chance to hear Pam expound on those ideas
at the Free to Be unschooling conference in Phoenix.)
