解读章首课，引领单元整体，落实数学素养——以七年级9.1节单项式乘单项式为例

Interpret the First Lesson of the Chapter, Lead the Unit as a Whole, and Implement Mathematical Literacy—Taking the Monomial Multiplied by the Monomial in Section 9.1 of the Seventh Grade as an Example

摘要: 随着数学核心素养的这一整体目标的提出，“单元整体教学”理念和实践拓展了新的教学视野，它是基于数学学科核心素养具有连续性、阶段性和整体性的特点提出的教学理念或主张。本文从解读章首课、在章首课中构建单元整体，从单元整体教学引领全章节，从而了解知识脉络、提供研究思路和方法，落实学生的核心素养。

Abstract: With the proposal of the overall goal of mathematics core literacy, the concept and practice of “unit whole teaching” have expanded a new teaching horizon, which is based on the characteristics of continuity, stage and integrity of the core literacy of mathematics. This article interprets the first lesson of the chapter, constructs the whole unit in the first lesson of the chapter, and guides the whole chapter from the overall teaching of the unit, so as to understand the knowledge context, provide research ideas and methods, and implement the core literacy of students.
