This competency-based preservice home economics teacher education module on influences on food prices is the fifth in a set of five modules on consumer education related to foods and nutrition. (This set is part of a larger series of sixty-seven modules on the Management Approach to Teaching Consumer and Homemaking Education [MATCHE]--see CE 019 901-967.) Following the module objectives and overview, two units of instruction are presented: (1) factors affecting food prices and (2) calculating actual food costs. Each unit includes the following elements: objectives, overview, narrative summary, suggested activities, and suggested resources. Also included in this module is a list of references on the evaluation of nutrient content, price, and palatability of brand names. A module pre/posttest (with answer key) concludes the document. (Workshop proceedings relating to the development of these modules are available in the ERIC system as CE 019 896-899; also available is a module on utilizing FHA-HERO as an instructional strategy to expand and strengthen the home economics instructional programs [CE 019 900].)
