纵观整个小学阶段的数学教学,计算教学占有相当大的比重。这个可从两方面来看:一是从各册教材的目录来看,计算教学占很大比重。二是从历届的小学数学考试试卷来看,计算类的试题分值就占40%以上,这还不包括综合运用中的计算。可见在小学阶段,计算教学有着极其重要的地位。而在计 Throughout the entire primary school mathematics teaching, computing teaching occupy a large proportion. This can be seen from two aspects: First, from the catalog of teaching materials, accounting for a large proportion of teaching. Second, from the previous primary school mathematics exam papers point of view, the calculation of the class question scores accounted for more than 40%, which does not include the calculation of comprehensive use. Can be seen in the primary school stage, computing teaching has an extremely important position. And in the meter
