This document discusses identifying and selecting aims for lessons. It explains that aims focus on functions, grammar structures, vocabulary, language skills, or topics. Good aims are based on what learners already know and need to know. Main aims describe the most important things to achieve, like practicing polite requests. Subsidiary aims show language or skills needed to meet main aims, like revising modal verbs. Personal aims focus on improving one's own teaching. After selecting aims, teachers choose teaching aids and materials and later check if aims were achieved. Aims describe what learners will learn, while procedures are the steps teachers and learners will take in the lesson.
