练习课是数学教学的一个很重要的课型,是新课教学的延伸和继续,是让学生掌握系统的数学基础知识,训练学生技能、技巧的重要途径,针对小学生的特点优化设计练习课,切实找到练习的训练点,通过这些训练点把数学知识串成一条线,形成一条数学知识链,对学生学习有一定的实效性。一、知识背景《除数是一位数的笔算除法练习课》在学生初步掌握了有余数笔算除法的方法和除数和余数之间的关系的基础上进行教学的。学生在上一节课完成了新授课的学习,对于笔 Practice lesson is a very important lesson in mathematics teaching. It is an extension and continuation of new lesson teaching. It is an important way for students to master the basic knowledge of mathematics and train students’ skills and skills. The practice lesson is optimized according to the characteristics of pupils. Practically find training points to practice, through these training points to math the knowledge into a line, forming a chain of mathematical knowledge, have some practical effect on student learning. First, the knowledge background “Divisor is a one-digit number division division practice class” in the students initially mastered the method of dividing the remainder of the pen and the divisor and remainder based on the relationship between the teaching. Students completed the new lecture in the previous lesson, for the pen
