Design or follow patterns with ease with this creative tool. The "slate" is a grid of encased steel balls that click to the surface using the magnetic stylus. Quickly draw a horizontal, vertical, or diagonal line, or pick and choose individual spots to work on. Erase quickly by sliding the stylus lengthwise over the entire surface, and you're ready for the next design. Recreate one of the designs on the 20 included cards in the slot at the top, or just doodle and see what you get. Use it as a no-mess art medium or a fun way to teach letter and number formation.
