Sequence
This example demonstrates the process of fraction addition. Key mathematical concepts include fraction addition and its geometric representation. Using GeoGebra commands such as Random, Vector, and Sequence, the geometric meaning of fraction addition is dynamically illustrated. Suitable for high-grade elementary and junior high school students to learn fraction addition and geometric construction.

GeoGebra Commands & Parameters

  1. Random(2, 10) → b
  2. Random(1, b) → a
  3. Vector((0, 2)) → j
  4. Random(1, b) → c
  5. Sequence(Rectangle[20 / b, ((k * 20 / b) - 5, 6), ((k * 20 / b) - 5, 4)], k, 0, b - 1) → list1
  6. Sequence(Rectangle[20 / b, ((k * 20 / b) - 5, 6), ((k * 20 / b) - 5, 4)], k, 0, a - 1) → list2
  7. Sequence(Rectangle[20 / d, ((k * 20 / d) - 5, 3), ((k * 20 / d) - 5, 1)], k, 0, d - 1) → list5
  8. Sequence(Rectangle[20 / d, ((k * 20 / d) - 5, 3), ((k * 20 / d) - 5, 1)], k, 0, c - 1) → list3
  9. Sequence(Rectangle[20 / b, ((k * 20 / b) - 5, -3), ((k * 20 / b) - 5, -5)], k, 0, b - 1) → list4
  10. Sequence(Rectangle[20 / b, ((k * 20 / b) - 5 + (m * 20 / b), 1 - (2 * n)), ((k * 20 / b) - 5 + (m * 20 / b), 3 - (2 * n))], k, 0, c - 1) → list7
  11. Sequence(Rectangle[20 / b, ((k * 20 / b) - 5, 6 - p), ((k * 20 / b) - 5, 4 - p)], k, 0, a - 1) → list6

AI Drawing Prompt Reference

Draw a geometric diagram illustrating fraction addition. Start by creating two horizontal rows of equal-width small rectangles at the top and bottom, each row representing a fraction unit, with one row partially filled to show the first fraction and the other partially filled for the second fraction. Then, in the middle, draw a full row of rectangles representing the sum, where some rectangles are merged or rearranged to display the total. All rectangles are aligned horizontally with equal widths, using filled versus unfilled sections to visually demonstrate the addition process.
