Penguins are cute little flightless birds which live mostly in sold places, close to the sea. These birds can swim a really long distance and also survive on land. Show your kids the pictures of the penguins and this worksheet and teach them some cool facts about the birds. Then, help your kids check the numbers next to the penguins to order them by height. Check the 5 next to the tallest penguin, and check the 1 next to the shortest penguin.
