教育家弗赖登塔尔提出了数学现实的理论,即数学教学应该和学生的现实生活联系起来,要让学生在生活实践中自主地得到知识。在小学数学两位数乘法的教学中也要遵循这一点,让学生在生活体验中学会数学方法,在实践活动中解决数学问题。教师在其中要起到引导和启发的作用,帮助学生融入数学现实中,理解两位数乘法的算理。一、思考交流,走出自己的数学现实《数学课程标准》指出学生所学习的数学内容应该是和现实有关的,具有挑战性而且有意义的内容,学生要通过自主观察、猜想、论证等方法来参与到这些数学学习活动之中。在两位数乘法的教学中,
The educator Freudenthal proposed the theory of mathematical reality, that is, the teaching of mathematics should be linked with the students’ real life, and let students acquire the knowledge autonomously in the life practice. In primary school mathematics double digit multiplication teaching should follow this point, so that students learn mathematical experience in the life experience, in practice to solve mathematical problems. Teachers should play a guiding and inspiring role among them to help students integrate into the mathematics reality and understand the arithmetic of double-digit multiplication. First, to think and exchange, out of their own mathematical reality “Mathematical Curriculum Standards” that students should learn mathematical content and reality-related, challenging and meaningful content, students through self-observation, conjecture, argumentation and other methods to Participate in these math learning activities. In double-digit multiplication teaching,
