Roman Numerals I to MM

With a farm of pigs as his abacus, Arthur Geisert uses elements of a search and count game to bring Roman numerals to life in this unintimidating math-concept book.First, the seven Roman numerals are equated with the correct number of piglets.Then the reader may practice counting other items-hot-air balloons, gopher holes, and more-as the remarkable adventure unfolds.(And yes, there are one thousand pigs in the etching for M!)
