CopanMobile for Palm 1.0.3
Free coordinate geometry (COGO) tool for field surveyors and map drafters. more>> CopanMobile for Palm is a very efficient and easy-to-use geomatics engineering tool for computing and managing plane survey coordinates. It does numerous coordinate geometry (COGO) calculations, processes and adjusts raw field survey data, computes and adjusts map traverse data, performs map checks, calculates curves, areas and perimeters, performs coordinate transformations, imports/exports Ascii files, and has GPS positioning and navigation functions.
It supports quadrant bearings as well as azimuths, and gons (grads) as well as degrees. Its coordinate files may be copied to the Palms memory card or to a removeable memory card and used directly by the Windows version of Copan.
Designed for land surveyors, geomatics engineers, professionals and students, CopanMobile for Palm is available for download, free of charge. A valid email address is required for a password and for news of updates.<<less

Quad2Go 0.7.2
Quad2Go offers you a powerful and easy-to-use tool for learning about quadrilaterals by generating examples, observing, and experimenting with examples with a view toward forming generalized conjectures. more>>
Quad2Go 0.7.2 offers you a powerful and easy-to-use tool for learning about quadrilaterals by generating examples, observing, and experimenting with examples with a view toward forming generalized conjectures. Explorations with Quad2Go are especially appropriate for 11-12 year old students. Teaching geometry to students of this age focuses on the critical attributes of quadrilaterals and on the hierarchical relations among them. Learning means identifying critical attributes and non-critical attributes.
For example, "four sides," "two pairs of parallel sides," or "two pairs of equal opposite angles" are some of the critical attributes of a parallelogram; "two long sides and two short sides" or "two acute angles and two obtuse angles" are non-critical attributes. Learning in this sense means learning to analyze the attributes of different quads, to distinguish between their critical and non-critical attributes, and learning the hierarchy among quads. Quad2Go provides many examples of randomly constructed quads. Each example can be changed by dragging either its vertices or sides.
Major Features:
- Similarly to frequently used Dynamic Geometry Environments (DGE) such as the Geometric Supposer, Cabri Geometry, and the Geometer Sketchpad, Quad2Go offers geometric objects, tools to manipulate them, and measurement tools. It is limited to quadrilaterals and the construction of diagonals.
- Quad2Go allows users to construct, view, and transform quadrilaterals compatible with the ones constructed with straight edge and compass, to measure lengths, angles, and areas, and to manipulate the construction by dragging and transforming its shape.
- Dragging allows changing a shape by direct translation of parts of its components on the screen. Learning by DGE is closely related to theories of constructivist learning, in which meaning is constructed through the learners active participation.

Fit2Go 0.7.1
Fit2Go provides you with a free linear and quadratic function graphing tool and curve fitter which supports exploration and modeling activities. more>> Fit2Go 0.7.1 provides you with a free linear and quadratic function graphing tool and curve fitter which supports exploration and modeling activities. It supports data collection by proposing a model that can appropriately describe the users data. The tool highlights the numeric aspects of a phenomenon. Together, Sketch2Go and Fit2Go provide a comprehensive view of models and modeling.
Fit2Go is suited for building a conceptual understanding of mathematical facts that are usually known only as "rules of thumb." Everyone knows that two points define a line. Fewer would know that three points define a parabola. High school students can prove it either in their algebra course by solving a system of equations or in their analytic geometry studies by implementing the geometric properties of the parabola. Fit2Go provides a wide repertoire of choices that fit given sets or subsets of data, and elicits questions and conjectures that can lead to formal solutions and proofs.
Major Features:
- Students can view a phenomenon, identify variables, conduct experiments, and take measurements in order to construct models of the phenomena.
- Fit2Go offers linear or quadratic models by presenting graphs and expressions of functions that can fit the data.
- Fit2Go provides an easy visual way of enter the data by dynamically viewing the point and reading its values.
- After choosing the type of model (an important decision that should be made by the user rather than automatically interpreted by the tool), Fit2Go presents a specific line (if only two data points are marked) or a specific quadratic function (if three points are marked).
- Interesting cases occur when too many or too few points are marked. Fit2Go does not attempt to fit a model to all points by interpolation. Rather, it randomly plots optional curves that fit a subset of the marked points and allows the user to alternate between the random options.
- If there are too few constrains, Fit2Go graphs a family of graphs, which it alternates according to the user requests.
