Introduction Each book in the Power Practice series contains dozens of ready-to-use activity pages to provide students with skill practice. The fun activities can be used to supplement and enhance what you are already teaching in your classroom. Give an activity page to students as independent class work, or send the pages home as homework to reinforce skills taught in class. An answer key is included at the end of each book for verification of student responses. Pre-Algebra provides activities that will directly assist students in practicing basic skills and concepts. The structure of the book enhances student learning and enables them to meet new challenges with confidence. Students will receive reinforcement in the following skills: determining divisibility finding common factors and multiples terminating and repeating decimals understanding integers and absolute value multiplying and dividing fractions finding and using percents using the order of operations finding the value of a given variable identifying and solving a monomial, binomial, or trinomial Use these ready-to-go activities to recharge skill review and give students the power to succeed.

Name Date Naming Number Sets Natural Numbers: The set of numbers that you use to count, starting with. Integers: The set of all whole numbers, both positive and negative. {..., - 3, -, -, 0,,, 3,...} Rational Numbers: The set of all integers plus all of the terminating or repeating decimals between the whole numbers. Irrational Numbers: The set of all numbers that are not rational. If a number is not rational, then it must be irrational. Write a number that fits the description.
