The first four months of school for eight first graders are chronicled in wonderful watercolor detail. Lines of text interrupted by numerous small pictures, perfect for sharing in laps or small groups, show a multi-racial class of children getting used to things on ``The First Day''a book corner, a box of dress-up clothes, the toilets, lockers, classroom routines, and saying goodbye to parents. Three other parts, ``The Second Day,'' ``Time Goes By,'' and ``Christmas Comes,'' follow with learning to read and write, show-and-tell, and the class rabbit who is finally named Ronald. Numerous pictures show the small school obstacles that each five year old must overcome. However, no book can depict the first year of school accurately for all audiences. Here, toilets flush with pull chains, children say a prayer at mealtimes and ``put on a play about baby Jesus'' at Christmas, dance in the gym in leotards and slippers, and swim each Friday in the school pool. Still, this school is a friendly place, and children everywhere share at least some of the experiences pictured. Susan Hepler, formerly at Windsor Public Library, Conn.
