In recent years pre-algebra has emerged as amajor topic in elementary and middle schoolmathematics. Not only does pre-algebraprepare students for the study of traditionalalgebra, it also fosters a student’s problem-solving skills, promotes the ability to expressmathematical relationships, and extends astudent’s overall proficiency in math.
The purpose of Practice, Practice, Practice!Algebra Readiness is threefold:
• To provide students with reproducibleactivities that will help them to master theskills and concepts of pre-algebra.
• To provide students with activities thatsupport the standards of the NCTM andthat serve as a foundation for the skills andconcepts found in the typical algebracurriculum.
• To provide students with activities that aremotivating, challenging, and fun.
What This Book ContainsThis book contains 52 reproducible activitiesthat focus on the skills and concepts of pre-algebra. The activities progress from basic tochallenging and are designed to meet theneeds of math students in grades 4 through8. The book begins with finding basicpatterns and advances through all of themajor skills associated with pre-algebra,including writing expressions, using the orderof operations, evaluating expressions, writingequations, solving equations, working withformulas, finding equalities and inequalities,and graphing ordered pairs. The activitiesrequire students to work with wholenumbers, fractions, decimals, percents, andintegers.
All of the activities are self-correcting.Students are presented with a question at thebeginning of each activity, which they cananswer by correctly solving the problems. Formost of the activities, a few problems that donot help to answer the questions are includedto make the activities more challenging. Thequestions that begin the activities are derivedfrom various subjects, including geography,history, science, literature, ecology, and popculture.
An answer key is included at the end ofthe book. The key shows the answers to eachproblem as well as the answers to thepuzzles.
