简单应用题即一步计算的实际问题,它是小学数学应用题教学的开端,对于培养学生问题解决的能力、深化学生数学思维品质具有重要意义。本文对简单应用题教学现状进行研究和分析,根据教学中及学生学习中存在的主要问题和现状,以比多比少的简单应用题为例,结合教学实践,形成以下课堂教学策略:第一,通过认数和计算教学,训练学生看图说话,在看图说话中渗透“同样多”、“相差”的概念,培养小学生的语言思维能力。第二,通过看说结合,大声读题,动手操作以及多样的思维训练来培养小学生的解题能力。第三,通过转换视角、设置情境、编题训练,培养小学生数学应用能力。第四,通过引导小学生养成检查的习惯,组织学生合作讨论,培养小学生自我评价能力。

Abstract:Simple mathematical word problems is one-step calculation of the practical problems.It is the beginning of mathematical word problems teaching in Primary Simple mathematical word problems teaching is very important for students' problem-solving ability and the quality of students' mathematical thinking. Study and analyze the simple mathematical word problems teaching situation, according to the main problems and current situation of teaching and learning,combining own teaching practice,to than less than of the simple word problems as an example, and form the following classroom teaching strategies: First, combined by identifying the number and calculation of the teaching to train students picture talk ,penetrate “the same amount, the difference” between concept by picture talk to develop language thinking ability of pupils.Second,combined by looking and speaking,read questions aloud,hands,and a variety of thinking training to strategies for develop the solving-problems ability of the pupils.Third,by changing view ,setting context ,and compile problems training to develop students’ ability of applying mathematical.Fourth,by guiding students to develop a habit of inspection and organizing students to discuss to develop the ability of self-evaluation of the pupils.
