The GraphGrid consists of a frame that is provided with rubber bands to create rows, columns and axes. Extra rubber bands are provided for additional lines or axes.
Also included are tools to draw standard graphs in a fast and efficient manner for math and science.

Games
A regular grid of cells, columns and rows can provide useful guidance. For example, creative drawings with repeating patterns in the cells. Many puzzles and games are played on a game board made up of squares, such as battleships and tic-tac-toe. In games like Yahtzee you can keep the scores by tallying in the squares. The higher rubber bands that are placed around the frame can be used to distinguish different parts of the game board or the scorecard.
School work
In school there are many applications where the ‘graphing paper’ of the GraphGrid is useful. Using the cells can help with learning to count or to learn the tables of multiplication. In secondary school, the GraphGrid is ideal to use in mathematics to draw graphs or make bar charts to present statistical information.
Mathematics
For example, construct a graph by using the grid as coordinates. Higher placed rubber bands can easily be identified as the x- and y-axis.
By adding one rubber band that crosses the X and Y axis a 3D coordinate system becomes available.
Additional rubber bands

The GraphGrid frame is already provided with rubber bands on arrival. However, additional bands are provided.
Tools for standard functions and graphs

The GraphGrid contains tools to create a graph for the standard functions: sine(X), cosine(X), tangent(X), X to the power of two and 1 divided by X.
Lenses: The topic of light in physics

The lens tool that is part of the GraphGrid enables to draw a convex and concave lens and also a mirror. These shapes are applied for the topic of light in physics.
