Third Grade Angels (A Rule the School Book)

Libro Usado, Tapa Blanda. George, aka "Suds," has just entered third grade, and he's heard the rhyme about "first grade babies, second grade cats, third grade angels, fourth grade rats," but what does this mean for his school year? It means that his teacher, Mrs. Simms, will hold a competition every month to see which student deserves to be awarded "the halo" -- which student is best-behaved, kindest to others, and, in short, perfect.
