This teaching guide on masonry building maintenance, one in a series of six publications designed for building maintenance instructors in Texas, is designed to give students an understanding of masonry construction. Introductory material provides teachers with information on use of the units of instruction and personalization and localization of the units. From the five units of instruction, each consists of eight basic components: performance objectives, suggested activities, information sheets (content essential for meeting the cognitive requirements), assignment sheets (application of knowledge), job sheets (procedures to give direction to the skills being taught), transparency masters, unit tests, and test and assignment sheet answers. The five units cover introduction to masonry, concrete finishing, masonry tools and materials, masonry construction, and masonry cleanup and repair. (YLB)
