A useful tool for the home or classroom, this coated wood board has a grid of 12 by 12 one-inch squares etched into the surface (for long-lasting durability) and raised wood border to prevent pieces from sliding off. Working in the grid encourages simple measurement, counting and aligning work as artists and architects do. The lightweight tray is 14 inches square and weighs 2 pounds. Made in China for ages 3+.
