由于小学生年龄小,思维灵活性较差。因此设计练习时要紧密联系教学内容,启发学生灵活运用知识,突破那些习惯的思维方式,找出解决问题的最佳途径,注意培养学生思维的灵活性。一、重视混合练习小学数学有不少相近、相似、相对的知识,小学生很容易混淆。针对这一特点,教师在教学新知识后,先进行一些单项练习,巩固新知识,再进行一些混合练习。如:在教学“两位数加减整十数”的口算之后,与“两位数减一位数”的口算进行混合练习:
Due to their young age, their thinking flexibility is poor. Therefore, the design practice should be closely linked to teaching content, inspire students to use their knowledge flexibly, break through those habits of thinking, to find the best way to solve the problem, pay attention to cultivate the flexibility of student thinking. First, attention to mixed practice There are many similar primary school mathematics, similar to the relative knowledge of primary school students can easily be confused. In response to this feature, teachers in the teaching of new knowledge, the first of a number of individual exercises to consolidate the new knowledge, then some mixed practice. Such as: teaching in the “two-digit plus and minus the whole number of ten” after the mouth count, and “double-digit minus one-digit” mouth practice mixed practice:
