CircleVectorSequenceGeometric Construction
This GeoGebra applet demonstrates equivalent fractions by randomly generating numerator and denominator pairs and representing them with circles, sectors, segments, and vectors. Core mathematical ideas include fraction equivalence, multiplicative relationships between numerators and denominators, and proportional reasoning. Construction highlights: Random and Sequence commands create dynamic fraction sets; Segment, Point, Circle, and Sector draw number‑line and area models; Vector visualizes magnitude; Textfield, InputBox, and Button provide interactive input and refresh. Suitable for upper elementary (grades 4‑6) fraction instruction and for teachers creating interactive lessons.
