The SMP pie chart scale is marked in percentages of the whole circle, so students can read from a pie chart or draw one from their data without the conceptual interruption of having to convert each percentage from or to an angle in degrees . Each pack contains ten pie chart scales. Referred to the SMP Interact books but suitable for use with any course.
