A great tool for practicing letter placement on the line, letter size and proportion. Each 8.5" x 11" board offers a hard surface on which to write and is two sided! Now you can have two versions in one. SGE-LM has 1" sized lines on one side and 3/4" lines on the other. SGE Wipe-Off Boards are fun and kids love them! Great for Kindergarten. Use with our Foam Alphabet letters SGE-UL and SGE-L.
