Plotting points; plotting products.

Welcome to the home site of the X•Y Chart. Our goal is to help your children do well in math by presenting three critical math skills in a special visual arrangement that organizes the multiplication facts in their true home in the first quadrant of the Cartesian coordinate system. It also suggests the importance of the variables X and Y. This brings together the most used operation, multiplication, with the most important visual tool of math, the Cartesian coordinate system, and connects them with the symbols X and Y that are central to algebra. We have done this with the help of two talented graphic designers who used visual techniques to make the chart easy to use and attractive, a piece of Mondrian-like art, that complements any home. Displayed there it sends the message: math matters.

Our most recent post offers you a short video which captures the essence of this multiplication table. It will explain our slogan: Plotting Points, Plotting Products. Please enjoy and let us know what you think about the chart.
