数学建模作为六大核心素养之一，在数学学习中有着举足轻重的地位，但是在实际教学中，数学建模往往被认为是应用题，常常处于被忽视的状态，数学建模课程也没有大范围推广开来，故而研究数学建模教学案例并用以实践是很有必要的。

为了更好的研究数学建模的教学案例，笔者通过问卷调查的方式，调查实习所在地高一年级学生的数学建模认知、数学建模能力和对数学建模学习的态度。发现学生对数学建模有一定的认知但不准确，相关能力有待提升，并且对数学建模的学习呈积极态度。

案例分析是推动教学设计的好途径，通过实地旁听对不同的案例进行总结和分析，可以取其精华，弃其糟粕，将分析结果用到教学设计中。本文摘取《茶水的最佳饮用时间》和《校车规划问题》两个一线课堂案例进行分析，以了解学生的接受程度、课程的设计板块、合适的教学活动。

基于调查结果和案例分析结果，笔者编写了一份高中数学建模和教学设计，主题为：在学校如何搭配早餐便宜又健康，并在实践过程中，结合学生反映不断改进。

Mathematical modeling, as one of the six core competencies, plays a crucial role in mathematics learning. However, in practical teaching, mathematical modeling is often considered an application problem and is often overlooked. The course of mathematical modeling has not been widely promoted, so it is necessary to study teaching cases of mathematical modeling and apply them in practice.

In order to better study teaching cases of mathematical modeling, the author conducted a questionnaire survey to investigate the mathematical modeling cognition, mathematical modeling ability, and attitude towards mathematical modeling learning of first-year high school students in the internship location. It was found that students have a certain level of understanding but not accuracy in mathematical modeling, and their related abilities need to be improved. They also have a positive attitude towards learning mathematical modeling.

Case analysis is a good way to promote teaching design. Through on-site audit to summarize and analyze different cases, we can take the essence, discard the dross, and apply the analysis results to teaching design. This article analyzes two frontline classroom cases, "The Best Drinking Time for Tea" and "School Bus Planning Issues", in order to understand students' acceptance level, course design sections, and appropriate teaching activities.

Based on the survey results and case analysis results, the author has written a high school mathematics modeling and teaching design, which theme is: How to pair breakfast with cheap and healthy breakfast in school. In the practical process, it has been continuously improved by combining student feedback.
