口算是提高学生计算能力的重要途径,能促进学生注意力、记忆力和创造性思维能力的发展。良好的口算能力不仅是学习其他数学知识的基础,而且计算的合理、简捷、迅速、正确也反映了一个人的数学素养。因此,在小学数学教学中,我们必须高度重视口算教学,提高学生口算能力。一、突出口算算理教学的地位要突出口算的算理教学,关键要让学生真正经历口算算理探究的过程。只有经常运用算理来进行口算,学生的思维才会得到有效的锻炼,心智活动才会得到良好的发展。现以“乘数是一位数的口算乘法”
Mouth arithmetic is an important way to improve students ’computing ability, which can promote the development of students’ attention, memory and creative thinking ability. Good oral ability is not only the basis for learning other mathematical knowledge, but also the calculation is reasonable, simple, rapid, correct and also reflects a person’s mathematical literacy. Therefore, in primary school mathematics teaching, we must attach great importance to oral teaching, improve students’ ability to calculate. First, highlighting the position of arithmetic teaching teaching To highlight the calculation of arithmetic teaching, the key to allow students to really experience the process of mathematical calculation. Only by always using arithmetic to conduct oral calculation, students’ thinking can be effectively exercised and their mental activities can be well developed. Now to “Multiplier is a single digit multiplication ”
