数学知识是由数学问题构成的,问题是数学的心脏,解题是学习数学的基本手段,无论是新知课、习题课、复习课还是讲评课,都离不开数学问题的解决。提高小学数学课堂的教学效率,必须以小学生数学学习程度为重点,因材施教,方能提高学生学习数学的兴趣和解题能力。“班内分层教学”就是利用题组组织课堂教学内容,整个课堂以解题活动为中心,让不同层次的学生解不同层次的习题,教师则根据学生在课堂上的思维表现和受阻情况随时调控,使小学生学习数学知识的渠道 Mathematical knowledge is composed of mathematical problems, the problem is the heart of mathematics, problem solving is the basic means of learning mathematics, whether it is a new lesson, exercise class, review class or comment class, are inseparable from the mathematical solution. To improve the teaching efficiency of primary mathematics classrooms, we must focus on primary school students ’mathematics learning ability and teach students in accordance with their aptitudes to improve students’ interest in mathematics and problem-solving skills. “Class teaching in layers” is the use of the group to organize classroom teaching content, the entire classroom to solve activity as the center, so that different levels of students solve different levels of exercises, teachers are based on the students in the classroom thinking and blocked The situation is regulated at any time so that pupils can learn the channels of mathematics
