    Tiger Math: Learning to Graph from a Baby Tiger

    A Siberian tiger cub born at the Denver Zoo, is orphaned when he is only a few weeks old. The veterinary staff raises him, feeding him by hand until he is able to eat on his own and be returned to the tiger exhibit. The story is accompanied by graphs on facing pages that chart T.J.'s growth, successfully showing math in "real world" terms. Easy-to-understand picture, pie or circle, bar, or line graphs, all with explanations, appear on the left; facing pages of text and clear full-color photographs are on the right. Overall, an innovative approach to teaching math.


    Lemonade for Sale

    Four kids and their sidekick, Petey the parrot, run a sometimes thriving lemonade stand whose patrons include all kinds of wacky neighbors—even a juggler.They create a bar graph to track the rise and fall of their lemonade sales. Illustrator Tricia Tusa has imbued the story with her delightful sense of humor and has made understanding bar graphs a breeze.

    Probably Pistachio

    "With Mom, Mondays mean it's probably pastrami. And pastrami is my favorite food in the whole world." Unfortunately for Jack, it's Dad's turn to fix lunch, and that's just the beginning of a bad day. In this MathStart entry, Stuart introduces the concept of probability. As Jack moves through his day, he makes a series of predictions based on good reasoning. As he thinks through the likelihood of each situation turning out in his favor, his thoughts appear in a cloud-shaped bubble above his head. Winborn's watercolors playfully depict Jack's misery as things go from bad to worse, until his bad luck finally ends when Mom brings home his favorite dessert, pistachio ice cream.

    No Fair (Hello Math Reader)

    Probability as it relates to fairness is the theme of this easy reader. When Kristy and David cannot agree on which game to play, David brings out a bag of marbles and says they can play Kristy's game if she chooses a blue marble, but Kristy objects when she learns that only one marble was blue.

    Introducing probability through games is appropriate, as children in this age group are very sensitive to fairness. Written in the style of a theatrical play for two readers.

    Measuring Penny

    Leedy offers another winning math-concept book. Lisa has a homework assignment to measure something in as many ways as she can, using standard and nonstandard units. "Use your imagination!" is the last instruction the teacher gives the students. Lisa chooses her Boston terrier and the fun begins. She measures Penny and a variety of other dogs. Lisa measures how much her pet eats, how high she jumps, how much time it takes to care for her, how much money is invested in her, how fast Penny runs, and a variety of other doggie traits.

    The results are shared with readers through charts, graphs, and reports. A great introduction to collecting data and a good story too.
