Teach your students how to plot points on a graph using ordered pairs from input-output tables with this set of teaching slides.
What Is the Cartesian Plane?
A Cartesian plane, also known as a coordinate plane or a coordinate grid, is a two-dimensional plane that is used to plot and locate points using a pair of numbers called coordinates. It consists of two perpendicular number lines, typically labelled the x-axis and the y-axis, which intersect at a common point called the origin.
How to Plot Points on a Graph
To plot a point on a coordinate grid, you can teach your students to follow these steps:
- Identify the coordinates of the point. Coordinates consist of an x-value (horizontal) and a y-value (vertical). For example, let’s say you want to plot the point (2, 3).
- Locate the x-axis and the y-axis on the grid.
- Find the x-value of the point you want to plot (in this case, 2) on the x-axis and move vertically until you intersect with the line that represents the y-value (in this case, 3) on the y-axis.
- Mark the intersection point with a dot or a small circle to represent the plotted point.
Remember that the scale and intervals on the axes determine the spacing between points. The grid may have labelled intervals, or you can estimate the placement based on the scale.
