The class is preparing to celebrate St. Patrick's Day and Katie, whose family is Irish, decides to make a shamrock for everyone in the first grade. Her parents describe what the shamrock looks like—three leaves that are heart-shaped. When Katie gets to school, her teacher pulls out a shamrock and shows it to the class, but it is nothing like Katie's. It has four leaves and they are not heart shaped. After she shows hers to her teacher, they go and look up shamrocks and sure enough, Katie's are correct. What the teacher has is a four-leaf clover. It is interesting, but it sure does not say much for that teacher. A Level 1 book in the "Ready-To-Read" series which contains tips for parents and teachers on the inside cover.
