What if animals and plants knew math, just like you? Would leaves fall in patterns? Would whales enter a race? In "Counting on Fall, " the first title in the "Math in Nature" series by award-winning author Lizann Flatt, nature comes to life to help children grasp concepts of number sense and numeration. The engaging "What if?" format of this informational picture book is sure to delight five- to seven- year- olds. Each of the four books in the "Math in Nature" series will cover one season of the year and one area of the math curriculum. Colorful, cut- paper collage art uniquely evokes the natural world, while two levels of text -- one a lyrical story, the other asking children to problem- solve -- bring the reader to a full understanding of the math concept being covered.
