教学内容:人教版小学数学三年级上册第六单元“口算乘法”例1、例2。教材分析:“口算乘法”是《多位数乘一位数》起始课,是后续学习笔算乘除法的基础。教材编排的情境图,旨在从学生熟悉和感兴趣的生活情境中发现数学信息,提出用乘法解决的数学问题。两幅小棒直观图呈现的是解决问题的策略,是把新知转化为表内乘法计算,体会口算乘法的算理和算法。这种数形结合的编排能帮助学生建立新旧知识之间的联系,渗透转化思想。学情分析:学生已经掌握了表内乘法和万以内数的
Teaching content: PEP primary school mathematics third grade sixth unit “mouth multiplication ” Example 1, Example 2. Textbook Analysis: “Mouth multiplication ” is the “multi-digit by one-digit” start class, is the basis for learning Penultimate multiplication and division. Situational maps of textbooks are designed to find mathematical information from life situations familiar to and interesting to students and propose mathematical problems solved by multiplication. Two small stick visual map presents a solution to the problem of strategy, is the new knowledge into the table multiplication calculation, understand the math multiplication of the algorithm and algorithm. This combination of numbers and forms can help students to establish the connection between old and new knowledge and infiltrate the idea of transformation. Student Analysis: Students have mastered the table multiplication and within the million
