“烙饼问题”是人教版教材第七册《数学广角》中的内容,主要通过讨论烙饼时如何合理安排操作最节省时间,让学生体会在解决问题中优化思想的利用。优化问题是人们经常要遇到的问题,我想从学生的生活经验和知识基础出发,创设问题情境,让学生通过观察、操作、实验、推理、交流等探究活动寻找解决问题的方法,从不同的方法中选择最 “Pancake problem ” is the seventh chapter of the PEP textbooks “Mathematics Wide Angle” content, mainly by discussing how to properly arrange the operation of the pancake to save time, so that students understand the use of optimizing ideas in problem solving. Optimization is a problem that people often encounter. I want to set up a problem situation based on students’ life experience and knowledge base so that students can find solutions to problems through observation, operation, experiment, reasoning, communication and other inquiry activities.
