Everything around you is a shape. Some are simple, like a circle or a triangle, and some are complex, like a snowflake or a star. And some are combinations of many shapes! In this volume, readers learn about a variety of shapes and how they're used in the world around them--especially when it comes to understanding math. As accompanying graphics present a visual element to each concept discussed, this volume provides readers with a helpful tool to explore shapes. They can even test their knowledge at the end of reading by taking a concluding quiz.
