This example demonstrates the process of dividing multi-digit numbers using an area model. Key mathematical concepts include division, area, and geometric construction. It utilizes commands such as Polygon, Point, Segment, and Intersect in GeoGebra. Suitable for upper elementary or middle school students learning multi-digit division.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → q1, a, b, c, d
  2. Point(d) → E
  3. Point(b) → F
  4. Segment(E, F) → f
  5. Point(a) → G
  6. Point(c) → H
  7. Segment(G, H) → g
  8. Polygon(I, J, K, L) → q2, i, j, k, l
  9. Intersect(k, l) → M
  10. Point(l) → N
  11. Intersect(i, j) → O
  12. Intersect(j, k) → P
  13. Polygon(M, N, O, P) → q3, m, n, o, p
  14. Segment(Q, R) → h
  15. Segment(S, T) → q
  16. Segment(U, V) → r
  17. Segment(W, Z) → s

AI Drawing Prompt Reference

Draw a figure consisting of a rectangle and a triangle. The rectangle represents a region, and the triangle represents a division part. The rectangle is connected by a line segment to another rectangle, and the triangle shares a vertex with the rectangle. Ensure the figure is clear and lines are simple, suitable for showing the area model.
