In spite of the considerable promise that computer technology provides for the improvement of school mathematics and student learning, the fulfillment of that promise has been stymied by issues of finance, access, and equity, among others
(Heid 1997, 2005).

What would it take for computer tools like spreadsheets, computer algebra systems (CAS), and interactive geometry, discrete mathematics, and statistics tools to become a more integral part of student learning and work?
• universal availability
• potential to be tailored for particular purposes
• curricula that incorporate these tools as an integral part of the development of mathematics (Heid 2005)

87% of U.S. teens aged 12–17 use the internet.
Of those, 87% have internet access at home.

Design Features
• The software toolkit was developed from the ground up with specific curriculum applications in mind.
• Tools were developed for each strand of the curriculum.
13
Algebra tools include an electronic spreadsheet and a computer algebra system (CAS) that produces tables and graphs of functions, manipulates algebraic expressions, and solves equations and inequalities.
The functionality of the CAS and other tools increases with each course level.
14
Geometry tools include an interactive drawing tool for constructing, measuring, manipulating, and transforming geometric figures, a simple object-oriented programming language for creating animation effects,
15
and a set of custom tools for studying geometric models of physical mechanisms, tessellations, and special shapes.
16
Statistics tools include tools for graphic display and analysis of univariate and bivariate data, simulation of probabilistic situations
17
and mathematical modeling of quantitative relationships.
Software includes pre-loaded data sets appearing in the student texts.
18
Discrete Math tools include tools for constructing, manipulating, and analyzing vertex-edge graphs and their representations as adjacency matrices.
19
Design Features
• The software toolkit was developed from the ground up with specific curriculum applications in mind.
• Tools were developed for each strand of the curriculum.
• Tools and their functionality are organized by course to focus on the intended mathematics and to reduce the steepness of the learning curve.
20
• Tools share similar menu screens and interface promoting learning transfer from one tool to another.
• Tools are built using Java WebStart, which permits safe, easy, and reliable distribution of software and software updates across different types of computers.
