固城中心小学集体备课教案（A lesson plan for the primary school in the central primary school）

固城中心小学集体备课教案（A lesson plan for the primary school in the central primary school） A lesson plan for the primary school in the central primary school Preparation for the class discussion paper: gao shigui (1) The teaching content subject Axisymmetric figure Discuss the record Teaching Suggestions class The first class The teaching goal The concept of axisymmetric objects and axisymmetric graphs is known. It is possible to judge whether the known graph is an axisymmetric figure, and it can be used to determine whether the common plane figure is axisymmetric and can be found to have several axis of symmetry. Through operation, cultivate students hands-on ability and infiltrate beauty education to students. Teaching important points The significance of axisymmetric graphics and the determination of which shapes are axisymmetric graphs and the axis of symmetry of common planar graphs can be found. Teaching difficult points It can be used to determine which figures are axisymmetric and can find the axis of symmetry of common planar graphs. The teaching method Preparation before class Autonomous learning style; The chalkboard and the film The teaching design Train of thought I. physical import Transition from axisymmetric objects to axisymmetric graphs. Examples: axisymmetric objects in life and common axisymmetric graphs. The concept of axisymmetric graphs, features and methods of judging are revealed. Find the axis of symmetry 1. Show a set of graphs and determine whether it is an axisymmetric figure. Look for the axis of symmetry by operation. 2. The students operate the operation, looking for the axis of symmetry of common plane graphs. 3. Consolidate practice Show the graph to judge, and find the axis of symmetry. Four, summary practice Design ideas Practice with a variety of shapes. Personal preparation: 2005-2006 academic year of solid city central primary school lesson plan Preparation for the class discussion paper: gao shigui (2) The teaching content subject Combi
