MathWise Decimals with Answer Key
The skill emphasized when learning decimals is place value. Place value is at the essence of understanding the meaning of digits to the right of the decimal point. If you regard the ones' place as a separate entity, then the places to the right of the ones' place mirror the places to the left of it. The places to the LEFT of the ones' place end in "s' (10s, 100s, etc.), while those to the RIGHT of the ones' place end in "ths' (10ths, 100ths, etc.).
While in Los Angeles, I devised a helpful framework that helped students to learn decimals: the "Rainbow Chart." It has a basic symmetry that helps students to understand the relationship of places to the left and right of the ones' place. After students master the Rainbow Chart in its most basic form, I replace some of the decimal values to include decimals and even negative exponents. The MathWise Decimals book includes reproducible pages for extra practice. The "D-Z" (Decimal-Zero) trick reinforces students' understanding of the Rainbow Chart and place value.
To properly understand decimals, students need to get a bigger picture by viewing them in relationship to fractions and percents. An understanding of decimals contributes to students' overall grasp of number sense.
Sometimes a little more practice is all that is needed to hone specific math skills. This series offers just that: topical practice, review, and extra practice. Peter Wise is a math teacher and author of this series that takes a fresh approach to helping students understand. The basics are intended for any grade level that might include them and are explained in a comic-style format. The books vary in length and are divided into one and two-page topical practices. Special features include tips and tricks (memory aids), speech bubbles with teaching insights, step-by-step procedures, simplified terminology to introduce concepts, and occasional concept quizzes. Each book goes from simple to more complex explanations and challenge problems are included to stretch students. Every topic includes explanations, samples, practice, and answer keys (not solutions) are found at the back of the book. There is plenty of room for students to work right in the book, and these are reproducible for a single classroom or family. This series is affordable, practical, and a great option for students struggling with specific concepts, needing more practice, or getting a jumpstart on new concepts. ~ Donna
