一、精选生活素材,让学生感悟数学数学来源于生活,生活中处处有数学。教学实践中,如能努力拓展小朋友们认识数学的空间,重视他们对数学经验的积累,让小朋友们在学习数学知识之前尽早感受。课堂教学就能收到事半功倍效果的。如在教学“高矮”的前一天,可安排学生:“明天数学课上,小朋友们要告诉全班小朋友,你家里是爷爷高些,还是奶奶高些?是爸爸高些,还是妈妈高些?同桌的是你高,还是他高?”这样学生在课外自然就会去认真观察比较,无形之中就把“高矮”的知识渗透到学生的生活实际中去感悟了。
First, the selection of life material, so that students understand mathematics Mathematics comes from life, life is full of mathematics. Teaching practice, such as efforts to expand the space for children to understand mathematics, emphasis on their accumulation of mathematical experience, so that children learn early mathematic knowledge before feeling. Classroom teaching can receive a multiplier effect. As in the teaching “Dwarf ” the day before, can arrange the students: “tomorrow math class, the children should tell the class of children, your grandfather is taller, grandma or higher? Is dad taller, or mom Higher? At the same table is your high, or he is high? ”So students naturally go to extra-curricular will be careful observation and comparison, invisible put “ dwarf ”infiltrated into the student’s actual life to feel .
