Supporting performance objective 22 of the V-TECS (Vocational-Technical Education Consortium of States) Secretarial Catalog, both a set of student materials and an instructor's manual on filing materials numerically are included in this packet. (The packet is the fourth in a set of nine on maintaining files and a library--CE 016 939-947.) The student materials include information on numerical filing, a self-check and student activity (with answer keys), final check-out activities; simulated index cards and business letters, and an instructor's final checklist. The instructor's manual includes directions for preparing the module for student use and an answer key for the final check-out activities. The materials are designed for self-paced individual instruction and may be adapted for use with large groups. (A separate booklet--CE 016 911--lists contents for the nine packets in this set along with those in several other sets--seventy-eight packets in all--based on the same V-TECS catalog.) (JT)
