This rhyming romp of a picture book introduces kids to the concept of skip counting with piles and piles of crocodiles, crews and crews of kangaroos, and more. How do you count lots and lots of ocelots? Or pile and piles of crocodiles? By 1s, 2s, 5s, and 10s, that's how! Children ages 5-7 learn the magic of skip counting--a key math skill in elementary curriculum--via silly rhymes and memorable groupings of animals. Engaging full color art encourages little fingers to count along, rhyming text encourages little voices to read along, and animal facts on every spread add an additional layer for rereading. Backmatter includes more skip counting activities and math support.
