IM Alg1.1.7 Lesson: Spreadsheet Computations

This GeoGebra example demonstrates how to use the spreadsheet view for mathematical computations, linking tabular data with geometric objects to visualize numerical operations and dynamic changes. Core mathematical concepts include percentages, angle measurement, spheres and dilation (homothety), and the Pythagorean theorem. The construction involves entering data, formulas, and functions in the spreadsheet, then connecting these values to geometric elements such as spheres, angles, and triangles for interactive parameter adjustment. Suitable for upper middle school or high school algebra courses, it helps students integrate algebraic calculations with geometric intuition and apply spreadsheet tools in mathematical modeling.
