整式的乘法是北师大版七年级下册第一章“整式的运算”第6节的内容,本节内容共分3课时,由浅入深地学习单项式乘单项式、单项式乘多项式、多项式乘多项式,三节课的知识环环相扣,每节课新知识的学习既是对前一节所学知识的应用,也为后一节学习奠定基础.所以在教学时要注意引导学生关注各知识点之间的联系,善于应用转化的思想,化未知为已知,形成较完整的知识结
The whole formula of multiplication is the content of the sixth chapter of the first chapter of the Beijing Normal University’s seventh grade book and the operation of the whole formula. The content of this section is divided into three classes. It involves learning monomials, monomial polynomials, and polynomials. By polynomial, the knowledge of the three classes is interlocking. The learning of new knowledge in each class is not only the application of the knowledge learned in the previous section, but also lays the foundation for the study in the latter section. Therefore, we must pay attention to guiding students to pay attention to each knowledge in teaching. The connection between the points is good at applying the ideas of transformation, turning the unknown into known and forming a more complete knowledge knot.
