Magnetic rods give kids tons of practice with counting, size discrimination and shape sorting! Each durable wooden rod is magnetic—and shows a number, shape or size for kids to match. Kids simply place magnets right on each rod…to count airplanes from 1 to 10, match a clock to the shape of a circle, sort adorable insects by size—and more! You get all 3 sets shown. Largest rod measures 11 1/2" in length. Each set also available separately.
