This tool helps students understand the concept of equivalent fractions through visual models. Students can see different fractions representing the same value in a visual way. The core math concepts involved include fractions and geometric construction. It uses commands like Polygon, Function, Point, Intersect, and Sequence in GeoGebra. Suitable for high-grade elementary and junior high school students.

GeoGebra Commands & Parameters

  1. Polygon(E, G, F, H) → poly2, e_1, g, f_1, h
  2. Function(w, 1.8 + poly2, 2.8) → wr
  3. Point(wr) → Q
  4. Intersect(xAxis, yAxis) → A
  5. Point(xAxis) → B
  6. Point(yAxis) → D
  7. Polygon(A, B, C, D) → poly1, a, b, c, d
  8. Sequence(Segment[(0, i / Horizontal), (1, i / Horizontal)], i, 1, Horizontal) → list1
  9. Sequence(Segment[(i / Vertical, 0), (i / Vertical, 1)], i, 1, Vertical) → list2
  10. Sequence(Segment[(1.8, i / HorizontaI), (2.8, i / HorizontaI)], i, 1, HorizontaI) → list1_1
  11. Polygon(J, R, Q, S) → poly4, i, j, k, l
  12. Sequence(Segment[(1.8 + i / VerticaI, 0), (1.8 + i / VerticaI, 1)], i, 1, VerticaI) → list2_1
  13. Polygon((1.8, 1), (2.8, 1), (2.8, 0), (1.8, 0)) → poly3, m, p, q, r
