Sequence
This example demonstrates the process of dividing a whole number by a fraction. Key mathematical concepts include fraction division. Using GeoGebra commands like Sequence, it dynamically shows each step of the division process. Suitable for upper elementary or middle school students learning fraction division.

GeoGebra Commands & Parameters

  1. Sequence(CircleSector[C, (x(C) + (r * sin((((i + 1) * 2) * π / d))), y(C) + (r * cos((((i + 1) * 2) * π / d)))), (x(C) + (r * sin(((i * 2) * π / d))), y(C) + (r * cos(((i * 2) * π / d))))], i, 0, c - 1) → list1
  2. Sequence(Circle[((((-(a - 1)) * 2.5) * r / 2) + ((k * 2.5) * r), 0), r], k, 0, a - 1) → list2
  3. Sequence(Sequence[CircleSector[((((-(a - 1)) * 2.5) * r / 2) + ((k * 2.5) * r), 0), ((((-(a - 1)) * 2.5) * r / 2) + ((k * 2.5) * r) + (r * sin((((i + 1) * 2) * π / d))), (r * cos((((i + 1) * 2) * π / d)))), ((((-(a - 1)) * 2.5) * r / 2) + ((k * 2.5) * r) + (r * sin(((i * 2) * π / d))), (r * cos(((i * 2) * π / d))))], i, 0, d - 1], k, 0, a - 1) → list4
  4. Sequence(CircleSector[(cent(f(k)), 0), (cent(f(k)) - (r * sin(((part(f(k)) * 2) * π / d))), (r * cos(((part(f(k)) * 2) * π / d)))), (cent(f(k)) - (r * sin((((part(f(k)) + 1) * 2) * π / d))), (r * cos((((part(f(k)) + 1) * 2) * π / d))))], k, 1, (floor(((a * d) - c) / ((4 * c)) + 1) * c)) → liste1
  5. Sequence(CircleSector[(cent(f(k) + c), 0), (cent(f(k) + c) - (r * sin(((part(f(k) + c) * 2) * π / d))), (r * cos(((part(f(k) + c) * 2) * π / d)))), (cent(f(k) + c) - (r * sin((((part(f(k) + c) + 1) * 2) * π / d))), (r * cos((((part(f(k) + c) + 1) * 2) * π / d))))], k, 1, (floor(((a * d) - (2 * c)) / ((4 * c)) + 1) * c)) → liste2
  6. Sequence(CircleSector[(cent(f(k) + (2 * c)), 0), (cent(f(k) + (2 * c)) - (r * sin(((part(f(k) + (2 * c)) * 2) * π / d))), (r * cos(((part(f(k) + (2 * c)) * 2) * π / d)))), (cent(f(k) + (2 * c)) - (r * sin((((part(f(k) + (2 * c)) + 1) * 2) * π / d))), (r * cos((((part(f(k) + (2 * c)) + 1) * 2) * π / d))))], k, 1, (floor(((a * d) - (3 * c)) / ((4 * c)) + 1) * c)) → liste3
  7. Sequence(CircleSector[(cent(f(k) + (3 * c)), 0), (cent(f(k) + (3 * c)) - (r * sin(((part(f(k) + (3 * c)) * 2) * π / d))), (r * cos(((part(f(k) + (3 * c)) * 2) * π / d)))), (cent(f(k) + (3 * c)) - (r * sin((((part(f(k) + (3 * c)) + 1) * 2) * π / d))), (r * cos((((part(f(k) + (3 * c)) + 1) * 2) * π / d))))], k, 1, (floor(((a * d) - (4 * c)) / ((4 * c)) + 1) * c)) → liste4

AI Drawing Prompt Reference

Create a visual diagram showing how to divide a whole number by a fraction. Start with one large circle representing the whole number, divided into equal sectors with alternating colors. Next to it, draw several smaller circles of the same size, each also divided into the same number of sectors, but highlight only a portion of each to represent the fractional unit. Use arrows or color coding to show how groups of sectors from the large circle map to the smaller circles, illustrating the division result. Keep the layout clean and educational.
