计算是小学生需要具备的基本数学能力之一,但是,在实际的教学过程中反映出的小学生数学计算能力情况却令人担忧。课改以来,很多教师也尝试用各种方式来提高小学生的数学计算能力,笔者结合实践,总结出几点解决的方法。一、创设有效情境,激发学生兴趣兴趣是学习的第一动力来源,学习兴趣的建立,可以帮助提升学生的学习效果。减法运算是教学的一个难点,需要教师耐心指导。例如“300-199=?”学生容易错误地把式子 Computation is one of the basic mathematical skills that pupils need to have. However, the mathematical calculation ability of primary pupils reflected in the actual teaching process is worrying. Since the curriculum reform, many teachers have also tried various ways to improve the mathematical ability of primary school students, the author combines practice, summed up several solutions. First, to create an effective situation, to stimulate interest in students interest in learning is the first source of motivation, the establishment of learning interests, can help enhance student learning. Subtraction is a difficult teaching, teachers need patient guidance. For example “300-199 =? ” Students easily mistakenly put formulas
