一、调动学生的多种感官,积极地参与教学活动。 小学生的思维离不开形象和动作,特别是低年级学生。教师必须根据低年级数学教材的特点,从学生的心理特征、思维特点出发,把数学基础知识的教学建立在直观的基础上,尽量把文字的东西变成直观的具体的东西。如:教学5+1和1十5时,先出示预先插好的小棒图,放在学生中间,使左右两边学生从不同的角度观察,可指名左边的同学看图说出算式,再指名右边同学看图说出算式。然后大家比一比计算的结果,评一评谁的算式对,为什么。使学生在对小棒数量的感知的基础上得出“调换两个加数的位置,和不变”这个规律。
First, mobilize the many senses of students, and actively participate in teaching activities. Pupils' thinking is inseparable from the images and movements, especially the lower grades. Teachers must base on the characteristics of the lower grade math textbooks, starting from the students' psychological characteristics and thinking characteristics, establishing the teaching of the basic knowledge of mathematics as an intuitive one, and trying to turn the characters into intuitive concrete things. Such as: teaching 5 + 1 and 1 ten 5, the first pre-inserted small stick figure, placed in the middle of the students, so that the left and right students from different angles of view, you can refer to the left side of the classmates figure shows the formula, then name the right Students see the figure to say the formula. Then we compare the results of a comparison, evaluation who evaluated the formula, and why. So that students in the number of sticks on the basis of the perception of “the location of the exchange two addends, and the same” rule.
