Fit2Go supports exploration and modeling activities. It supports data collection by proposing a model that can appropriately describe the user's 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.

Features

Fit2Go is a linear and quadratic function graphing tool and curve fitter. 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.

Suggested Activities

Construct a function with a given values-table

a value table is given:

Start by graphing the points on paper. Chart and write down the expression of the function you conjecture would best fit the points.

Enter the order pairs as points into Fit2Go

Click on the points to which you wish to fit your model and choose a family that you think is a good candidate for fitting the points you have selected.

Find relationships between the height of a ramp and the time it takes a skateboard to travel the length of the ramp

If possible, let the students set up an experiment and take measurements. Assume a specific constant length of the board. If it cannot be done, use some data sets that could fit such an experiment

Consider what happens to the run time when the board becomes flatter. Or higher. Could the runtime be zero? Could it be a linear model?

Graph2Go Graph2Go - Graphing calculators are instrumental in teaching and learning mathematics. It is an environment that supports conceptual understanding of functions in general, and school algebra and real analysis in particular. Especially, it enhances connections between graphic and symbolic representations

Quad2Go Quad2Go - 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

Sketch2Go Sketch2Go - encourages visual exploration of phenomena by providing qualitative indication of the ways in which the sketch drawn by the user changes. The sketch is a diagrammatic representation that attempts to help the viewer focus on the principles rather than on tedious details of the represented phenomenon. Phenomenon can refer to processes outside of mathematics (e

Solve2Go Solve2Go - supports solving equations and inequalities by means of conjectures based on visual thinking. Conjectures can be refuted or supported by examples provided by the tool, and should be proved using symbolic manipulations on paper.
