From Organization / 国外机构评价: |
| This latest math concept story featuring Penny the Boston terrier tackles a subject more difficult than that presented in Measuring Penny (1998) and Mapping Penny's World (2000). Lisa's teacher assigns the class to study probability by writing down predictions, determining results, and recording them. He demonstrates by using (and eating) jellybeans. Choosing Penny as her focal point, Lisa begins to calculate her results: Will Penny want to go for a walk? (Of course.) What might happen? (Perhaps she'll see a squirrel.) What won't happen? (She won't see a shark.) Using her familiar not-quite-naive style of illustration, Leedy clearly and cleverly depicts the possibilities and choices in panels and segmented pages that feature Penny in funny poses. The amusing jacket, which pictures the perky dog wearing cool sunglasses and a beaded collar, is an enticing beginning. Prediction: this will work well as a learning device. Julie Cummins |
Foreign Customer Review / 国外客户评价: |
| This Loreen Leedy educational book reviews linguistic/mathematical applications of probability, as explored by young Lisa using her dog Penny as the object of several "thought experiments." It's packed with information; so dense, in fact, that adult readers may want to omit some pages with younger audiences. However, Leedy's humorous characterizatrion of school, Lisa's teacher, and especially that cute black dog balance the relatively high cognitive load, rendering a very entertaining book that edges out most of the math-oriented competition.
WE begin with Lisa's teacher, Mr. Jayson, who teaches Lisa and her classmates the differene between things that possibly, might, and will occur. THe kids write down what Mr. Jayson might wear that day, and hefools them all with hat that looks like a sea cucumber with orange toes, and two suspended eyeballs! "'I don't usually wear hats,' he says. But as you can see, it is possible.'" He moves on to picking different-colored jelly beans while closing his eyes, showing how the pool of jelly beans from which he chooses affects whether he will, might, or can't select a certain color (and, luckily for him, eating a lot of jelly beans while doing so!) There's a nice realism here as well: One student asks: "Why are we doing all this?" "It's for homework," the teacher replies. "We all groan. But he lets us eat the rest of the jelly beans, so that helps." That's good, because they have a monstrously long assignment: Examples of things that will, might, and can't happen, tiny chance vs. impossible, and equal vs. unequal chances of ouccuring.
Fortunately, Lisa's dog (someday as famous as Schoedinger's cat?)helps her answer all those questions. Although the "will" example is a little shakey ("I'm sure Penny will want to go on a walk."), and has more to do with hypothesis testing, "might" is convincing (Penny might see a squirrel on their walk), "can't" is funny ("We can't see a shark because the ocena is 50 miles away.") Later when Penny sees a toy shark--the book is full of sly surprises--Lisa says that doesn't count! LIsa also makes notes to help her decide whether there's a tiny chance of Penny eating an entire birthday cake, finding a pirate treasure chest, or becoming a famous canine actor, or whther these things are impossible. This is a great departure for classroom or group discussion. Perhaps mindful of recent history, Lisa defends at great lengths her decision that a Penny Presidency would be impossible.
There are even more examples of equal and unequal probabilities, and these require a bit of mathematical/logical reasoning that may be too advanced for youngers. However, Leedy offers a wide range of kids the opportunity to compare event probabilities, and to see how concepts like might, can, and will occur with some frequency in daily life. COmbine that with creatively formatted (bordering on manga presentations), brightly colored picturs, and lots of tangential but humorous background about Lisa's family and Penny, and your youngster will probably enjoy this book. There's no getting around the fact that hte book is teaching one about math, counting, logic, and language, but the humorous, casual narrative, and Leedy's involvement of the reader in Lisa's problem immeasurably increase its appeal. |
