Children are fascinated by shapes and colors and the world is full of amazing shapes, colors, and sizes. Look and you can see that a wing on a flea is a triangle, a ruler is a rectangle, and the wheels on a truck are circles. Using vivid illustrations and a simple rhyming text, noted author/illustrator Ed Emberley introduces the concept of shapes and sizes to curious young children as he suggests they view the world in a new and exciting way.
