《义务教育数学课程标准》指出,应当立足于学生固有的知识和实际生活经验,以使学生自己感受,通过数学模型抽象实际问题,且加以应用和解释,从而加深对数学知识的把握。尽管小学生的年龄比较小,可是学生的实际生活经验也比较丰富。为此,在小学数学教学实践活动中,教师需要有效地统一实际生活和教学知识,以提高学生的数学意识,且可以通过数学知识对平时生活中的问题进行解决,这也是所有小学数学教育工作者们认真探究的一 The standard of compulsory education mathematics curriculum points out that students should deepen their knowledge of mathematics by basing themselves on the students’ inherent knowledge and actual life experience so that students can feel their own feelings and abstract practical problems through mathematical models and apply and explain them. Although the primary school age is relatively small, but the actual life experience of students is also relatively rich. Therefore, in the practice of primary school mathematics teaching, teachers need to effectively unify the actual life and teaching knowledge in order to raise students’ mathematical awareness and to solve problems in daily life through mathematical knowledge. This is also why all primary school mathematics education work One who seriously explored
