LEVEL I-A UNIT AREAS COVER THE MEANING OF "NUMBER," ADDITION, MULTIPLICATION, SUBTRACTION, AND DIVISION. LEVEL I-B COVERS INTRODUCTION TO COMMON FRACTIONS, COMBINING FRACTION, FRACTIONAL PARTS, SEPARATING FRACTIONS, AND APPLICATIONS. EACH UNIT UNDER I-B HAS SUBDIVISIONS, WITH A PARAGRAPH OF TEACHING HINTS AND EXAMPLES. STRESS IS UPON CONCRETE EXAMPLES, WITH TERMS INTRODUCED AFTER UNDERSTANDING AND WITHOUT UNDUE EMPHASIS. THE TEXTBOOK MAY BE USED AS A SOURCE FOR EXAMPLES AND PROBLEMS AFTER AN IDEA HAS BEEN GRASPED. GENERALLY, TEXTBOOK DISCUSSIONS ARE TOO ABSTRACT FOR USE BY TALENT PRESERVATION STUDENTS. COOKBOOKS, SEWING INSTRUCTIONS, AND MAGAZINES SUCH AS "POPULAR SCIENCE" AND "POPULAR MECHANICS" ARE EXAMPLES OF GOOD SOURCES FOR PRACTICAL WORK WITH FRACTIONS.
