When it comes to problemsolving strategies, who hasn't heard of the "guess and check" method? This handbook of math strategies by Edward Zaccaro offers some innovative and easytoapply strategies such as the "Think 1" method. If the following problem (One bag of cat food will feed 3 cats for 40 days. If I buy 2 more cats, how long will one bag of cat food last?) makes your head hurt, then you definitely need to learn how to "Think 1." What I like about this book is that the author really takes his time explaining each strategy, and he also makes it fun by using cartoon characters. Each new strategy is then followed by lots and lots of practice. In fact, the practice problems are even separated into 5 levels of difficulty – Level 1, Level 2, Level 3, Einstein Level, and Super Einstein. This enormous book is divided into 17 chapters: Think 1, The 210 Method, Sometimes You Must Subtract, Draw a Picture, Venn Diagrams, Language of Algebra, Solving Equations, Solving Algebra Problems, Logic, The Power of Ratios, Function Machines, Don't Be Fooled, The Eccentric Mathematician, Permutations, Understanding Bases, Who Wants to be a Googolillionaire, and Contests. The last chapter, titled Contests, does not teach a new strategy but contains even more pages of practice organized into 45 problem math contests. 320 pgs. ~ Anh

Edward Zaccaro takes a different approach to what is needed to be successful in the fields of math and science. He looks at catastrophes and disasters of the past and how they are linked to thinking errors. He sites the Challenger explosion as being avoidable had management listened to the mathematical data of the engineers. The ten things he refers to in this book are things we don't generally teach, but they are very important. They are: Math and Science Will Tell You the Truth, Your Mind Can be Fooled (Counterintuitive Thinking), Occam's Razor (the most basic or simple reason), Mistakes and Frustration are a Part of Learning and a Part of Life, It is Important to Keep an Open Mind, It is Important to Maintain a Healthy Skepticism, Don't Be Fooled by Statistics, You Must Know the Difference between Cause and Correlation, Ethical Decision Making and Bias is Everywhere. These aren't typical topics we think of as being associated to math and science! Zaccaro uses a comic strip to present the idea for each chapter. He then uses cartoon characters throughout the chapter as he makes his point. Each chapter ends with 3 discussion questions. Over 50 stories are included to show children the strong connections between mathematics and science and the real world. 242 pgs, pb. ~ Donna

This is one book that I can honestly say lives up to its title. These math investigations are fascinating, reallife, and even downright scary. Chapter 1 is entitled: "The Nightmare of Payday Loans." You can see where this is going! So many adults fall into the payday loan trap; this investigation shows students why and how you quickly dig a hole you can't climb out of – just by doing the math. The next chapter is: "CornBased Ethanol is the Answer to Our Dependence on Foreign OilOr Is It?" This one hits close to home for us Midwesterners. The next three chapters are about Media Math Mistakes (Parts 1, 2, and 3). "Lawmakers Make Math Mistakes," "Be Careful When You 'Rent to Own,'" and "How People Lie with Statistics" are among the other very interesting investigations. Not only is the material sure to grab their attention (and ours), but the presentation is engaging, too. Two characters, an Einsteinlooking man and a professoriallooking rat, guide students through each chapter. They dialogue in word balloons, conversing about the unfolding investigation. After completion of the investigation, there are four activities (Level 1, Level 2, Level 3, and Einstein) that apply and expand on the knowledge and skills obtained during that investigation. The book wraps up with, "Prices Were Really Cheap When My Parents Were Young! Or Were They?" It sure seems like it to me, but I'll have to do the math to find out for sure! Complete answers with solutions are provided in the back.
