Roman Numerals I to MM: Numerabilia Romana Uno Ad Duo Mila

The porcine stars of Pigs from 1 to 10 teach kids to do as the Romans do in this numerical excursion. As Geisert exhorts readers to ""count the number of pigs to find the value of [the seven single-letter Roman numerals],"" pale pink pigs proliferate, romping on jungle gyms and seesaws, swimming, splashing, until, upon reaching ""M,"" the pages are swarming. Parental guidance may be needed for those readers who lose count of the pigs on the way to 1000. Once the basics are conquered, Geisert explains how to add and subtract numbers to make other numbers (e.g., VIII). Again the pigs demonstrate, in a fancifully conceived barnyard cum playground setting rendered in Geisert's characteristically subdued palette. The mathematical adventure continues as readers practice newly acquired skills by hunting down XV balloons, IX ducks in a pond, etc.; the spreads become more colorful as piglets take to the air in festive balloons and head off on a field trip. As always, Geisert's detailed etchings reward extended perusal, and children will revel in the sheer abundance of pigs. A great lesson in Roman numerals, this book scores a certain X. All ages. (Apr.)
