This example demonstrates the concept of equivalent fractions using visual models. Core math concepts include fractions, geometric representations, and proportional relationships. It is constructed using GeoGebra commands like Polygon, Function, Point, Intersect, and Sequence. Suitable for upper elementary and middle school students to understand the fundamental properties of fractions and the visual representation of equivalent fractions.

GeoGebra Commands & Parameters

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

AI Drawing Prompt Reference

Create a geometric diagram to demonstrate the concept of equivalent fractions, featuring a rectangle divided into multiple smaller rectangles and connected lines to show the geometric representation and proportional relationships of fractions. Start by drawing a rectangle, then add smaller rectangles inside it, connect key points with lines, and finally link the edges of the rectangle to the inner rectangles with curves to form a visual model of equivalent fractions.
