A math T-chart is a method used to organize information in two columns in order to solve problems or for graphing equations. In math, a T-chart is very useful for keeping a list of corresponding "x" and "y" when given either a linear or quadratic equation to graph. To make this chart, it is necessary to draw a long T-shape that has two columns.
At the top of the chart, an "X" and "Y" are placed to represent the values for the variables of an equation, such as the linear equation y = 2x + 6. A student choose values for "x" like 0, 1, 2 and 3 to get corresponding values for "y" of 6, 8,10 and 12. Each value picked for "x" goes under the X column and the corresponding values for "y" go under the Y column. In this manner, the student creates a table of values which can then be plotted.
