Seeing Factors: Visualizing Divisors and Remainders in Division

① This interactive GeoGebra example visualizes the relationship between factors and remainders in integer division, making abstract arithmetic concepts tangible. ② Core mathematical concepts include divisibility, factors, remainders, the division algorithm (dividend = divisor × quotient + remainder), and foundational ideas of sequences and functions. ③ Construction highlights: uses Sequence to generate ordered points, Segment to draw factor partitions, Max to compute the largest factor, Textfield and inputBox1 for user input, button1/button2 for toggling views, and lists (ListV, ListH, RH, ListRV) to organize data, creating a dynamic visual model. ④ Suitable for upper elementary to middle school students learning factors and division, as well as for classroom demonstrations or self-guided exploration—users can change the dividend and divisor to observe how factors and remainders change.
