Lakeshore Size Sorter Magnetic Rods

Magnetic rods give kids tons of practice with size discrimination! Each durable wooden rod is magnetic and has a small, medium, or large bug at the top. Kids simply sort the bug magnets by size to match the bug at the top of each rod! The set comes with 9 rods and 45 magnets; the largest rod measures 10 5/8 inches in length.
