This teacher resource is fun for learning and for play time! Children put the puzzle pieces in place to hear the zoo animals' sounds. This is a colorful and tactile way to teach kids what their favorite animals sound like, as well as matching and problem-solving skills. It's a durable classroom aid that will last year after year!
