“式与方程”是“数与代数”领域的教学内容。这部分内容是学生从算术的学习转向代数的学习的重要转折点,它们是后续学习数学的重要基础。通读苏教版教材后,认为苏教版教材中“方程”的编排结构有如下特点。一、交错渗透与独立编排相结合 “Equation and equation ” is the teaching content in the field of “number and algebra ”. This part is an important turning point for students to switch from arithmetic learning to algebra study. They are the important foundation for further study of mathematics. After reading the teaching materials of the Sujiao Version, the structure of the “Equation” in the teaching materials of the Sujiao version has the following characteristics. First, the staggered penetration combined with independent programming
