Number formation and counting to 20 are a breeze—with our handy all-in-one center! Kids just place a card on the left side of the board…follow the directional arrows to trace the number with a finger…then use the attached stylus to write the number on the magnetic surface. When they’re done, children slide the eraser bar to clear their work…and flip the card over to count a matching quantity of objects! Sturdy plastic board includes 20 double-sided activity cards and a guide. Board measures 10 3/4" x 14 3/4".
