Measure It with Math!

Did you know cheetahs can run 70 miles per hour? How do we know this? In this book, readers learn how to measure speeds like that of a cheetah using a simple formula and metric and imperial units. Diagrams, illustrations, and photographs further illuminate the knowledge presented and help readers fully grasp the concept. A concluding activity teaches readers to measure their own speed and puts their knowledge to the test.

Time is measured in a variety of units, including seconds, hours, days, weeks, and decades. This practice began with the sundials of ancient Egypt, but we still use clocks and calendars today to keep track of our time. This volume guides readers through measuring time, figuring out time zones, and learning about classic and modern timepieces. Through a fun activity and introductions to some famous scientists, readers will gain a better understanding of the measurement of time.

Even if objects are about the same size, that doesn't mean they're the same weight. Readers will learn about many units that measure weight and about concepts such as density, gravity, and mass. With colorful photographs and engaging illustrations of ancient and modern scales, this book will help readers learn facts about weight, including how boats float and how weight is a factor in baking.

The ancient Romans certainly had a hand--and foot--in the way we measure distance today, but modern technology has advanced measuring techniques considerably. Scientists have used nanotechnology to make the study of even minuscule distances more tangible. Readers discover this information and much more through text and illustrations as they learn about the concepts involved and the tools used to measure distance.

Temperature can determine a multitude of things, such as if someone has a fever or if your dinner is fully cooked. Readers will learn many aspects of measuring temperature, including using a thermometer and navigating the two most common scales, Celsius and Fahrenheit. Key math concepts are made understandable through hands-on activities, problems to solve, and engaging graphics.

To build a house or paint a room, a person must know how to calculate the area of the space. Readers will learn ways to calculate area using height and length through this book's understandable diagrams, illustrations, and photographs. Examples from real-world experiences will bring the exercises to life, and readers can apply their knowledge to solving the math problems featured throughout.

Not even a gigantic tape measure could capture the height of the tallest buildings in the world, so how do we know this information? Readers learn the answer to this question and more through fascinating photos and intriguing facts that introduce them to the units of height. Imperial and metric measurements are provided to guide readers as they learn about calculating altitude and estimating height. With real-world examples and problems to solve, this volume allows readers to immerse themselves in the concepts.

Volume, the amount of space that a substance or object occupies, is an important math concept for readers to grasp. This book guides readers to learn the simple formula for finding volume. The information provided is accompanied by vibrant photographs and engaging illustrations. Readers learn about shapes--both regular and irregular--as they solve for exact volumes or estimates. Student comprehension is reinforced with a hands-on activity that allows them to apply their knowledge.
