Sharpen your observation skills! Take out your magnifying glass and join Caillou and his friends as they play detective and search for hidden objects in wonderfully busy places, including the county fair, the barn, the aquarium, and many more. There are so many things to see! The book contains large illustrations each bursting with colorful creatures and objects. An illustrated list indicates the number of objects to find--a fun way to introduce little ones to numbers 1 to 10! Includes additional look-and-find activity ideas!
