This GeoGebra example demonstrates a visual sorting and matching activity for multiples by placing numbers around a circle. The core mathematical concepts include multiples, divisibility, distribution of points on a circle, and set correspondence. Construction highlights: the Shuffle command randomly permutes a list of numbers, Element extracts individual items, and Circle creates the reference circle. Objects include ten number points A1 to J1 and ten circle positions P1 to P10, with lists listp and listq controlling the mapping between numbers and positions, while variables aa to jj and mm adjust parameters. Suitable for upper elementary to middle school students to practice multiples, and useful as a math game or interactive classroom activity to build intuitive understanding of multiples and divisibility.
