Modeling: The Function Sketcher   Design: Michal Yerushalmy, Beba Shternberg. Programming: Alexander Zilber, Gil Semo Draw & Tell: The Function Sketcher" is a learning environment for modeling using visual signs rather than symbols of algebra. As such it is suitable for learning the mathematical language of modeling even before starting algebra studies. It can be used for learning about functions in junior-high , or within topics such as functions, derivatives, analyses and physics in high school. The environment provides students the linguistic terms and the graphic images of functions. Models are determined by specifying a list of properties or with matching graphic representation from a library of icons. In both ways the resulted graphs can be then manipulated, dragged or analyzed. The software with its built-in activities is designed to build a foundation for algebraic connections between language and graphs throughout activities that require students to make judgments based on context, and model real world stories. The Function Sketcher is one of three in a set “Modeling”. Before using this software it is recommended to use: “Modeling: MoveOn”- introducing of graphs representing phenomena, realizing the need in graphs as mathematical objects. After using The Function Sketcher is recommended to use: “Modeling: Escalator”- setting change of a graph - the derivative of the function (a constant change or a linear change or an exponentional change) and to getting the appropriate function.
