Globe Newswire reports that Dr. Iris Mack's mathematics edutainment book is "turning heads across the country in a response similar to the widely promoted 'Hooked on Phonics, ' that improved children's reading skills." Her unique approach to math became one of Xlibris/Random House Publisher's top children's picture book royalty earners. If there is one word that sums up our recent economic woes, it is interest. There's interest on credit card balances, student loans, car loans, home mortgages, corporate borrowings and most prominently, on state and national debt. But there is surprisingly little interest in this interest. We all pay it. But not many of us really understand how it works. Dr. Iris Mack has filled the gap - and for young consumers. Her financial literacy book "Mama Says Money Doesn't Grow on Trees '' is focused on teaching students that math can be fun and key to understanding money and interest. In today's world of subprime mortgage crises, bankruptcies, massive credit card debt and predatory lending, Dr. Mack's book is more relevant than ever. In "Mama Says Money Doesn't Grow on Trees " a group of smart, animated characters explain how money and interest work, as young consumers are introduced to mathematics and financial literacy. Professor O, Ms. Madonna Sorenson and Dr. Mackamatix lead students Al G Bro, Frakshun, Nada, Queen% and Material Girl Ma$ through a fun-filled math class all about how money and interest work in their everyday lives. "I think the work you do showing how math can be beautiful and practical is great, keep it up " says Javier Tordable, Senior Software Engineer at the Google Corporation. "Making math fun and relevant is a real public service. Old fashioned, boring textbooks aren't the thing that will capture the imagination and engage our children in the fun and yes, joy, in math and problem solving. Iris Mack has created a group of characters and scenarios that will draw young people into the fold of knowledge." says Karen Pritzker- Producer of The My Hero Project and Editor of The Yale Center for Dyslexia & Creativity website. The print and eBook versions of the financial literacy book "Mama Says Money Doesn't Grow on Trees " are available for sale online at Amazon.com, Walmart.com and other channels.
