A second-grade teacher shows a book, The Tortoise and the Hare,to his class. The book has no words, only pictures. In the fable, the tortoise moves slowly and steadily while the hare runs very fast but is so confident that he will win the race that he stops to take a nap, thus losing the race to the tortoise. When asking his students what the story means, one of the students says, “It means that tortoises are slow and the hare should have won.” Which of the following best describes the area with which this student needs further practice?
