This video shows how you can create two- and three-dimensional space on the TactiPad by using rubber bands placed diagonally around the frame of the GraphGrid.

03. GraphGrid – Trigonometry tool
With the GraphGrid comes a new drawing tool that can be used to draw trigonometric functions, as is explained in the following video.
02. GraphGrid – Games, counting and keeping score
By placing the GraphGrid on the TactiPad, you create a flexible grid that can be used for playing games, keepinig the score or learning to count. This video shows how this works.
01. GraphGrid – Introduction
This video shows the characteristics of the GraphGrid, the accompanying drawing tool and how it can be placed on the TactiPad drawing board.
01 GraphGrid: getting started

The GraphGrid is a frame with rubber bands that fits on the TactiPad. It includes four additional tools: hyperbole, parabola, sintang and lens. The configuration of the bands in rows, and/or columns and axes gives it its functionality for X/Y and 3D coordinate systems. For a description of the graph grid frame and on how to modify the configuration of the rubber bands, see the section: GraphGrid frame
For applications of the GraphGrid frame, see the sections:
03 Games and scores
04 Connecting dots; house, cube and more
05 Simple bar chart
06 Drawing a graph in a coordinate system
07 3D coordinate system
The additional tools are applied without the GraphGrid frame. Drawing the axes with the ruler is sufficient.
