I found an easy-to-understand definition of accredited homeschooling on Wikipedia: Accreditation is a type of quality assurance process under which a facility's or institution's services and operations are examined by a third-party accrediting agency to determine if applicable standards are met.

In primitive geometrical terms, an ellipse is the figure you can draw in the sand by the following process: Push two sticks into the sand. Take a piece of string and form a loop that is big enough to go around the two sticks and still have some slack.
The Ellipses Gizmo starts by relating the formula of an ellipse to the formula of a circle, which is a special type of ellipse. Students then explore the Pythagorean relationship, which allows the position of the foci to be determined. In addition, the Gizmo helps make sense of the definition of an ellipse, which can be a tricky one. An ellipse is a curve created by moving a point so that the sum of its distances from two fixed points (the foci) is constant. Thatâs tough to picture, but the draggable purple point in the Gizmo illustrates it nicely. It also is a perfect lead-in to the hands-on activity of actually drawing an ellipse using a compass, a loop of string, and two push pins.
