FunctionSequenceGeometric Construction
This example demonstrates the process of fraction addition. Key mathematical concepts include fraction addition. Using GeoGebra commands such as Point, Polygon, LCM, Sequence, etc., a geometric model of fraction addition is constructed. Suitable for high-grade elementary or junior high school students to learn fraction addition.

GeoGebra Commands & Parameters

  1. Point(Circle[A, 1]) → B
  2. Polygon(A, B, C, D) → poly1, a_1, b_1, c_1, d_1
  3. Point(Circle[E, 10]) → F
  4. Polygon(E, F, G, H) → poly2, e, f, g, h
  5. Polygon(I, J, K, L) → poly3, i, j, k, l
  6. Polygon(A, B, M, N) → poly4, a_2, b_2, m, n
  7. Polygon(H, E, O, P) → poly5, h_1, e_1, o, p
  8. Polygon(I, J, Q, R) → poly6, i_1, j_1, q, r
  9. LCM(b, d) → s
  10. Sequence(Segment[(((10 * i)) / b, 0), (((10 * i)) / b, 1)], i, 1, b - 1) → list1
  11. Sequence(Segment[(((10 * i)) / d, -1), (((10 * i)) / d, -2)], i, 1, d - 1) → list2
  12. Sequence(Segment[(((10 * i)) / s, -3), (((10 * i)) / s, -4)], i, 1, s - 1) → list3
