Session 7, “Circles and Pi,” of Learning Math: Measurement investigates the properties of pi and its relationship to the measures of a circle.
What do carpets have to do with pi? See practical applications of pi in the Math in Daily Life interactive. This section of the interactive demonstrates its value in home decorating.
Elementary students use string and tape measures to approximate the value of pi in the lesson "Round About Pi."
