Printed on poster board, this 13” x 19” laminated charts can be used with dry erase markers for graphing practice. On the reverse of each poster is an 8.5” x 11” reproducible of the same image on the front of the chart.
X-axis is numbered -20 to 20 and Y-axis is numbered -30 to 30.
Imagine the tangible properties of a geoboard with an XY graph. Simply slide the clear X and Y lines over the red board to allow yourself the proper graphing proportions, set the included white pegs to match your coordinates, then use the included rubber bands to connect points as necessary. A really neat way to take graphing off the page. – Laura
