## Description

_Pre-Algebra World: Number Sense_ is an edutainment title intended to teach
pre-algebra mathematics – a broad set of of mathematical techniques beyond
basic arithmetic that are intended to prepare a student to learn elementary
algebra. This program takes the form of several multimedia activities unified
by the loose premise of exploring a planet. Each section of the game offers
its user a chance to not only learn the theory behind a mathematical concept,
but several chances to practice and drill on them in order to further increase
their understanding. Throughout this process, they are guided by an abstract
creature named Google, who can be called on to give hints and advice
throughout the activities.

There are five major sections in _Pre-Algebra World_. The first teaches
students how to deal with very large and small numbers through the use of
place values, as well as showcasing various historic numeral systems. The
second teaches them how to round numbers and estimate the results of an
arithmetic calculation. A third part focuses on integer factorization and
demonstrates various techniques for doing so. The fourth section introduces
the concept of fractions, and it relies heavily on the concepts taught in the
previous section. Finally, an “arcade” is included which contains various
small activities that build off the knowledge students have learned in
previous sections, with a focus on visual representations of these concepts.
