几何设计图以实际生活为载体 ,体现了数学内容与现实生活的联系 ,使试题的求解体现了观察、操作、猜测、验证、推理等探究过程 ,考查了学生实践能力和探究问题的能力 ,因此成为中考命题的新热点 .本文提出几例 ,希望能给读者一点启迪 .例 1 如图 1有一服装厂里有大量形状为等
The geometric design diagram takes real life as the carrier, embodies the connection between mathematics content and real life, and makes the solution to the question reflect the process of observation, operation, guessing, verification, reasoning, etc., and examines the students’ ability to practice and explore the problem. It has become a new hot spot in the examination proposition. This article presents a few examples, hoping to give the reader a little inspiration. Example 1 There is a large number of shapes in the clothing factory as shown in Figure 1.
