度过愉快的暑假,同学们又开始了新的学习旅程。下面,和同学们一起梳理“分数乘法”单元的学习内容。这单元的内容主要有分数乘法、解决问题和倒数的认识三个部分,这些内容是后续学习分数除法和百分数知识的重要基础。同学们要联系学过的整数乘法、分数的意义和性质等知识来理解和掌握有关“分数乘法”的知识。 After a pleasant summer vacation, the students started a new study trip. Now, together with your classmates, review the learning of the “fractional multiplication” unit. The main contents of this unit are three parts, namely, fractional multiplication, problem solving and reciprocal understanding. These contents are important basis for subsequent learning of fractional division and percentage knowledge. The students should understand and master the knowledge about “fractional multiplication” in connection with the multiplication of integers, the meaning and nature of fractions.
