Teaching content: PEP Primary 4 grade mathematics books on the 64 ~ 65 pages. Teaching Objectives: 1. Preliminary understanding of the vertical and parallel is the same plane two straight line two special relationship between the position, so that students understand the concept of vertical and parallel. 2. Through the observation, classification, comparison, imagination and other exploration activities, so that students gradually form a space concept. 3. To guide students with independent thinking, cooperative exploration of learning awareness, perception of life in the vertical and parallel phenomenon, stimulate students interest in learning mathematics. Teaching heavy, difficult: to enable students to understand the concept of vertical and parallel. understanding
