Making Sense of Integers

So far in the Core Advantage system, students have learned how to add, subtract, multiply, and divide positive numbers. However, the world is full of both positive and negative numbers. Consider the following: 1. Temperatures can go both above zero and below zero. 2. A mountain can be thousands of feet above sea level, while a submarine can go thousands of feet below sea level. 3. A house can either increase or decrease in value. 4. Money can be deposited into or deducted from a bank account. This is why integers are so important - they help us understand more of the world around us. Adding, subtracting, multiplying, and dividing integers are full of nuances, and students must pay attention to these details. This book, Making Sense of Integers, will help students notice these details so they can gain fluency working with integers.
