2022 年，我国教育部发布《义务教育课程方案和课程标准（2022年版）》并指出要积极开展主题化、项目式学习等综合性教学活动。项目式学习能够促进学生通过小组合作解决真实问题，从而习得知识、发展思维、提升多元能力、树立正确价值观，是我国当下促进学生深度学习和培养学生核心素养的有效路径。目前我国小学数学项目式教学实践仍在经历探索和尝试，小学数学深度学习还有待推进。

本研究通过收集整理项目式教学与深度学习的国内外相关文献，明确项目式教学与深度学习的本质内涵，了解深度学习与项目式学习在小学数学阶段的理论和实践现状。基于相关理论，初步构建小学数学深度学习过程模型，分为学习导入、浅层学习、深层学习和全程评价四个部分。构建小学数学项目式教学流程设计，包括选题分析、项目设计、项目准备、项目实施四个阶段。根据构建教学流程设计，选取小学数学人教版六年级上册《确定起跑线》展开教学设计，并以 P 小学六年级两个班的学生为研究对象实施教学，根据教学效果进行反思。经过项目式教学，学生的学科知识、学科素养及其他跨学科得到提升，数学学习兴趣得到提高。

In 2022, China's Ministry of Education issued the Compulsory Education Curriculum Plan and Curriculum Standards (2022 edition), and pointed out that comprehensive teaching activities such as thematic and project-based learning should be actively carried out. Project-based learning can promote students to solve real problems through group cooperation, so as to acquire knowledge, develop thinking, improve multiple abilities, and establish correct values. It is an effective way to promote students 'deep learning and cultivate students' core literacy in China. At present, the project-based teaching practice of primary school mathematics in China is still undergoing exploration and attempt, and the deep learning of primary school mathematics still needs to be promoted.

By collecting and sorting out relevant domestic and foreign literature of project-based teaching and deep learning, this study clarifies the essence of project-based teaching and deep learning, and understands the theoretical and practical status of deep learning and project-based learning in primary school mathematics. Based on relevant theories, the deep learning process model of primary school mathematics is preliminary constructed, which is divided into four parts: learning introduction, shallow learning, deep learning and whole-process evaluation. Construct the primary school mathematics project-type teaching design process, including four stages: topic selection analysis, project design, project preparation and project implementation. According to the construction process of teaching design process, the second volume of "Determine the Starting Line" of primary school mathematics teaching edition is selected to carry out the teaching design. The students of two classes of grade six of a primary school are the research object to implement teaching and reflect according to the teaching effect. Through project-based teaching, students' subject knowledge, subject literacy and other interdisciplinary subjects have been improved, and their interest in mathematics learning has been improved.
