Editorial Reviews

Children's Literature
In this book, students learn about comparative value, an important concept for understanding place value, equating measurements and understanding equations. Mike and his brother Andy collect dinosaur cards. Andy has just turned seven and his parents are letting him go to the Dinosaur Card Trading Fair for the first time. He and Mike have big plans to get a T. Rex card. At the last fair, Mike found a girl who wanted three Allosaurus cards for the T. Rex card. Mike and Andy must wheel and deal thirteen cards to eventually put together the right combination to garner the cherished T. Rex. All the while the clock is running out. The big surprise is what Mike does with the card when he gets it. A Level 3 book from the "Math Starts" series. 2001, HarperCollins, $15.95. Ages 7 to 10. Reviewer:Kristin Harris
School Library Journal
Gr 2-4-Using dinosaur trading cards as a theme, Murphy explores the concept of equivalent values. Mike and his brother, Andy, go to a trading fair in hopes of finding a Tyrannosaurus rex card. By making various trades they are successful in getting the coveted item. The story contains just the right amount of tension as well as tidbits of dinosaur facts interspersed among the math concepts. Colorful pictures of enthusiastic traders in dinosaur masks and hats add interest. A concluding page gives suggestions of various math activities that correlate with the book. Teachers and students alike will find this one a winner.-Anne Knickerbocker, Cedar Brook Elementary School, Houston, TX Copyright 2001 Cahners Business Information.
Kirkus Reviews
Murphy continues to amuse with math-quite a trick considering the amount of anxiety the subject manages to generate. Here he tackles the concept of comparative value by working it into a story of trading cards. Mike and his brother Andy are dinosaur trading card enthusiasts. It's Andy's birthday and as a special treat he is getting to accompany older brother Mike to a trading fair for the first time. Mike is in hot pursuit of a Tyrannosaurus rex card, but he has to wheel and deal to get the cards the owner of the T. rex wants in trade. As the story progresses, small boxed items on the page allow readers to see the action in terms of equations-two Pterosaur cards equals one Stegosaurus card, four of which equal one Tyrannosaurus card-and also learn a few facts about the dinosaurs. And sweetly, at the end of all the furious trading Mike gives Andy the card for his birthday present. O'Malley's color-shocked artwork is a real plus to Murphy's story, which easily takes the mystifying sting out of comparatives. A guide is included to help kids get the most out of the book, and a few games are suggested to enjoyably extend the math lesson. (Picture book/nonfiction. 7-9)
