Dry-erase board features a dual-sided design with an axis grid on one side and a plain side on the other to offer twice the amount of space. Bold lines separate the board into quadrants to help students create accurate graphs. Write-and-wipe surface will not ghost to prevent the surface from dulling over time. Hardboard backing will not warp or chip for long-lasting use. Dry-erase board is perfect for academic practice, doodling and more.
