    As taught in school books, analytic geometry can be explained more simply: it is concerned with defining and representing geometrical shapes in a numerical way and extracting numerical information from shapes' numerical definitions and representations. Transformations are ways of shifting and scaling functions using different algebraic formulas.

    The program is aimed at children between the ages of 9-12. [7] Squeak is a modern, open-source, full-featured implementation of the Smalltalk language and environment. Smalltalk is an object-oriented, dynamically typed, reflective programming language created to underpin the "new world" of computing exemplified by "human-computer symbiosis". [8]

    A third grade project growing out of the day-to-day life of the nearby Hudson River became one of the most celebrated units of the school, a unit on boats, which under the guidance of its legendary teacher Miss Curtis, became an entrée into history, geography, reading, writing, arithmetic, science, art and literature. Each of the units was ...
