[ 책 소개 ]
MathStart 시리즈는 어린 아이들이 일상생활 속에서의 사례를 이용해 수학의 기본 개념을 쉽게 이해할 수 있도록 구성되어 있습니다. 재미있는 Story와 그림을 통해 영어와 수학의 두마리 토끼를 함께 잡을 수 있습니다.
사막에 사는 코요테들이 모여서 점심 요기거리로 로드런너, 도마뱀, 메뚜기를 잡아 먹으려고 합니다만, 그 전에 이런 먹이감들이 주위에 몇 마리가 있는지 세어봅니다. 코요테들이 지역별로 분담을 해서 각자 센 숫자를 합쳐 정확한 숫자를 세는 것도 좋지만, 영리한 코요테는 반올림 방법을 이용해서 근사치를 계산해 냅니다. 이 책에서는 반올림을 해서 복잡한 계산을 쉽고 빠르게 만들어 근사치를 구하는 방법을 배울 수 있습니다.

Book Description
Clever Coyote thinks it's time for lunch -- and also time to show her friends how, with some simple rounding, she can add up numbers in her head. If only she were as good at hunting as she is at math!
Children's Literature
Clever Coyote and his four friends Careful, Cool, Clumsy, and Little One are counting various critters that they would like to eat for lunch in the desert. Careful, Cool, Clumsy, and Little One individually count some of the tasty treats and, then, add their numbers together to determine the sum of the tidbits available. Clever Coyote impresses his friends by mentally rounding each of their answers to the nearest ten, then, adding the rounded numbers to get a close approximation of the total. They appear to be so busy counting and adding that they never catch any of their prey. This humorous book, with the included suggestions in the back, could be used in the classroom to reinforce the concept of rounding numbers. The colorful illustrations of desert creatures are very well done. Facts about some of the desert inhabitants are scattered throughout the book. This is part of the "MathStart" series. 2003
Library Journal
Taking a fun approach to math, this book introduces the concept of rounding to estimate the sum of several numbers. A group of coyotes stands in front of a desert ranch and wonders how many roadrunners live in the area. They split up, and each one counts the ones that he or she sees. When they are ready to add their numbers, Clever Coyote rounds each figure to the nearest 10, adds them together, and quickly comes up with a close approximation of the actual total. The procedure is repeated with lizards and grasshoppers. Humorous watercolor cartoons depict the action and clarify the concept. Charts help to illustrate how each number is rounded. Factoids about coyotes and other desert creatures appear throughout, so readers learn not only math, but also get their fair share of science sprinkled into the mix. A section entitled "Adults and Kids" includes math games, book suggestions, and ideas for turning grocery shopping into an estimating experience.
