Dual-sided, pre-printed lines on one side and blank on the other offer endless uses. The blank side works great for classroom games, math lessons, and reminders. While our pre-printed side is great for penmanship and sentence writing. Durable masonite lap boards are 9" x 12" and can be used with all dry erase markers. An environment-friendly way to learn, as you just write, wipe off, and re-use with no waste. Pack of 6 boards.
