This example demonstrates sorting rational numbers on a number line. It involves core math concepts like rational numbers, number line, and sorting. Construction highlights include commands like Polygon, Segment, Sort, If, RandomElement, and objects such as b, Cdenom1, A, etc. Suitable for middle school and above, focusing on rational number comparison and number line representation.
