Hands-on x, y coordinate experiences!

Divided into the traditional four quadrants, the Pitsco Coordinate Geometry Board invites students to plot x, y coordinates; find the slope of a line between two points; graph a line; learn various quadrant characteristics; approximate areas of geometric figures; and much, much more!

This attractive, sturdy, 11" x 11" board is designed with 121 peg holes that snugly hold grooved wooden pegs. Simply insert pegs in various holes (x, y coordinates) and use the colored rubber bands to show various line segments. Holes are also available on both the x- and y-axes.

Contains the board, 25 pegs, and a bag of colored rubber bands.
