A great tool for practicing letter placement on the line and letter size/proportion. Each 8½" x 11" board offers a hard surface on which to write and is two sided! Now you can have two versions in one. SGE-MS has 3/4" sized lines on one side and 1/2" lines on the other. SGE Wipe-Off Boards are fun and kids love them! Useful for Kindergarten and up.
