This example demonstrates geometrically what happens when dividing by decimals, focusing on area models. It involves core math concepts like division, decimals, area calculation, and geometric modeling. Constructed using GeoGebra commands like Point, Polygon, Segment, it is suitable for middle school and above students to understand the visual geometric meaning of division operations.

GeoGebra Commands & Parameters

  1. Point(Circle[I, abs(f)]) → J
  2. Polygon(I, J, 4) → poly3, l, m, n, p, K, L
  3. Point(Circle[E, abs(e)]) → F
  4. Polygon(E, F, 4) → poly2, g, h, i, j, G, H
  5. Segment(I, J) → k
  6. Point(Circle[A, abs(sqrt(divisor))]) → B
  7. Segment(A, B) → a
  8. Polygon(A, B, 4) → poly1, b, c, d, q, C, D
