This video shows the characteristics of the GraphGrid, the accompanying drawing tool and how it can be placed on the TactiPad drawing board.
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.
With the GraphGrid comes a new drawing tool that can be used to draw trigonometric functions, as is explained in the following video.
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.
