This example demonstrates comparing and identifying fractions on a number line. It involves core math concepts like fractions, percentages, ratios, addition, and coordinate geometry. Construction highlights the use of GeoGebra commands such as SelectedElement, IndexOf, Segment, Sequence, Textfield, OrthogonalLine, Intersect, Mode, If, Element. Suitable for middle school mathematics teaching or self-learning to understand the relationships and positions of fractions.

AI Drawing Prompt Reference

Draw a number line and mark several fraction points, such as 1/2, 1/4, and 3/4. Connect these fraction points with line segments. Create a slider to adjust the positions of these fractions and observe their changes on the number line.
