IM Geo 1.22 Lesson: Now What Can You Build?
Loading the math board and drawing, please wait…
This GeoGebra example is part of the Illustrative Mathematics Geometry curriculum, Lesson 1.22, designed to guide students in synthesizing prior geometric construction and transformation skills to build complex figures freely. It demonstrates how to use a text input field (Textfield) to dynamically control parameters, while organizing a multi-step construction with numerous named objects (pic1 through pic37). Core mathematical concepts include geometric construction, translation, fractal geometry, logical reasoning, and geometric mean, all within an open-ended problem-solving context. The construction highlights the use of the Textfield command to create interactive inputs, base points A and B, a variable n to control iteration or fractal depth, and a series of picture objects (pic series) to layer visual components. This resource is suitable for upper middle school or high school students, fostering geometric intuition, logical thinking, and creative design skills. It also serves as a valuable template for teachers planning inquiry-based lessons.

Textfield(n) → InputBox1
AI Drawing Prompt Reference
Create an interactive drawing with an input box that controls a single parameter n, representing iteration depth or fractal layering. Use two base points, A and B, as the starting reference to set positions and directions for all subsequent construction steps. Then follow a multi-step process that builds and layers many geometric components (a sequence of picture-like layers), where each layer’s contribution is determined by the value of n. The resulting figure should reflect geometric construction together with transformations, forming a fractal-style design that updates dynamically as n changes.
