American footballs are often made of leather, rubber, or even plastic covers and as a result, don't exactly get soaking wet like a tennis ball would. Which is why football games often continue in the rain. And if a basketball was shaped like a football it would have a much tougher time passing through the net. These are just a few fun facts about the field of sports that are highlighted in this nursery rhyme picture book geared toward early readers. The poem helps the young readers to identify which type of ball goes with each sport along with a well-known feature. The rhyming format makes it fun to sing along and facilitates memorization. Preschoolers to second graders respond well to sing-songy books so purchase one for your little one today and start singing!
