This workbook is designed as an easy-to-read, slower-paced mathematics text for students who have learning, reading, and language problems. Helping students fulfill mathematics requirements for graduation is a goal; the book can be used as the core or supplement to the mathematics curriculum in mainstreamed or special education classrooms, in mathematics laboratories, or as part of sheltered workshop and vocational training programs. Basic concepts and skills about decimals and percents, including computation with decimals and using proportions to solve percent problems, are presented. All 10 units begin with a brief discussion of how decimals or percents are used in real life and list a few key words. Lessons teach only one major concept per page. A comprehension exercise ends each lesson, usually with answers given on the page so students can quickly check their mastery. Most lessons are reinforced with at least one worksheet, available in the teacher’s guide. The units are titled: Decimals Are Part of Our Lives, Comparing Decimals, Adding and Subtracting Decimals, Multiplying Decimals, Dividing Decimals, Percents, Ratios, Proportions, Solving Percent Problems, and Renaming Decimals and Percents. A short glossary is included. (MNS)
