UNIT SPECIFIC OBJECTIVES CONTENT TEACHING AND LEARNING ACTIVITIES EVALUATION UNIT 3 ELECTRICAL AND PLUMBING SYMBOLS UNIT 4 INTERSECTIONS OF STRAIGHT AND CURVED MOULDINGS The students will be able to 3.3.1 identify basic electrical and plumbing symbols. 3.3.2 prepare drawings of basic electrical and plumbing symbols. 3.4.1 identify types of mouldings. 3.4.2 determine intersections of straight and curved mouldings. 3.4.3 draw mouldings in the same plane. 3.4.4 determine the true shape of mitres. Electrical symbols (e.g. socket, fan, bell, switch. Plumbing symbols (e.g. bath, WC, sink, showers. Drawing of electrical and plumbing symbols. Types of mouldings (straight and curved. Intersections of straight and curved mouldings. Mouldings in the same plane. True shape of mitres. Show charts to students to brainstorm on electrical and plumbing symbols. Discuss the basic electrical and plumbing symbols using sketches or charts. Using charts, show students the basic plumbing and electrical symbols. Guide students to use the symbols to prepare simple drawings. Using charts and models, show types of mouldings in the same plane. Group students to brainstorm the principles of intersections of straight and curved mouldings. Illustrate various methods of determining types of intersecting mouldings and assist students to practice. Use models to illustrate types of mouldings in the same plane. Guide students to draw types of mouldings in the same plane. Use charts to illustrate how to determine true shape of mitres. Guide students to determine true shape of mitres.
