Visualizing Squares from 2 to 20

This GeoGebra example demonstrates how to visualize the sequence of square numbers from 2 to 20, making the growth and discrete structure easy to see and compare. The key concepts include sequences and series (a discrete sequence of values) and the square function as a simple but foundational building block for understanding how one quantity depends on another. The construction uses the provided commands and objects: RandomElement and Random to pick and vary elements (e.g., a, b, c, A, B, C, D, d, and related labels), Simplify to keep the computed forms clean, and on-screen objects pic1 plus text1/text2 to present or annotate the active terms or results. Designed for students learning sequences and function patterns, it works well for classroom demonstrations and exploratory learning.
