REGULAR MAIL ORDER CATALOGS MAY BE USED AS A SOURCE OF MATERIAL FOR TEACHING MANY PRACTICAL LESSONS TO GROUPS OF STUDENTS WHO MAY BE POTENTIAL DROPOUTS. A UNIT CENTERING ABOUT THE USE OF SUCH CATALOGS WAS DEVELOPED IN A CLASS OF STUDENTS 14 YEARS OF AGE OR OLDER BUT STILL IN ELEMENTARY SCHOOL. LOOKING UP AND ORDERING ITEMS FROM A CATALOG CAN AFFORD MANY OPPORTUNITIES FOR INSTRUCTION IN ARITHMETIC, VOCABULARY BUILDING, AND CHOICE MAKING. THE PRESENT UNIT GREW OUT OF A NEED TO TEACH THE STUDENTS PROPER ATTIRE. USE OF CATALOGS ATTRACTED THEIR IMMEDIATE ATTENTION. THE UNIT ON CLOTHING GREW INTO OTHER UNITS ON BUSINESS AND INVESTIGATING VARIOUS TYPES OF MATERIALS USED IN CLOTHING. INFORMATION LISTED IS INTENDED PRIMARILY FOR THE TEACHER, BUT MATERIALS ARE INCLUDED THAT CAN BE USED BY PUPILS. (APPENDIX CONTAINS INFORMATION ABOUT CLOTHING, VOCABULARY, AND APPLICABLE ARITHMETIC PROBLEMS.)
