Picture Book Review: Time for School Nathan

Time for School Nathan by Lulu Delacre, Scholastic Books, New York, 1989.  This book is about how to maintain your friendships through changes in life.  Nathan is an elephant heading to his first day of kindergarten.  However his mouse friend wants to go as well, and feels jealous that Nathan may make new friends.  He sneaks to school, and almost ruins Nathan's first day.  However when they agree to be friends, the little mouse friend is able to accept the change and let Nathan go to school alone.  Th artwork appears to be chalks, but I am no expert.  Some of the pictures, especially the outside scenes, have some very nice colors.
