小学阶段是学生计算能力培养的关键时期,作为“运算能力”核心要素之一的“估算”在学生运算能力提升中起着举足轻重的作用。“具有估算意识和初步的估算能力”是《小学数学课程标准》中明确提出的教学要求。面对学生计算能力普遍下降的现状,结合课程标准精神,我们数学教师要高度重视估算教学,在教学中加强学生估算意识和能力的培养,以提升学生运算能力。一、体验估算价值,养成估算习惯估算在数学学习和日常生活中应用广泛,估算有助于培养
The primary stage is a crucial period for the students to develop their computing abilities. “Estimation”, which is one of the core elements of “computing power”, plays a decisive role in improving students’ computing ability. “Estimation and Preliminary Estimation Ability ” is the teaching requirement explicitly stated in the Standard for Primary Mathematics Curriculum. Faced with a general decline in students’ computing abilities, in line with the standard of curriculum standards, our math teachers should attach great importance to the evaluation of teaching and enhance students’ awareness and ability in teaching so as to enhance students’ computing abilities. First, to experience the estimated value, to develop an estimated habit Estimate in mathematics learning and daily life is widely used, the estimate will help to train
