If You Were Me and Lived in Russia by Carole P. Roman
I won this book in a give-away for my grandkids. It tells children an introduction to the culture of Russia, the food, the money, activities and customs. It is a cute little read and is part of a larger series. As we are from a culturally rich family, and I am a genealogist, this book series is of special interest to me! I think your kids would enjoy it, also!
