【背景描述】苏教版小学数学中的乘法始于二年级,贯穿整个小学数学并根据学生的认知水平逐步推进。乘法教学中,要求学生掌握算理,会进行笔算和口算。但是在实际生活中乘法口算的应用非常广泛。为了提高学生的口算能力,教师会有意识地布置一些口算练习,但在无人督促的情况下,往往无法落实。在一次课间活动的时候,看见女同学边唱儿歌边跳皮筋,那么长的儿歌她们记得那么清晰,而且在你追我赶中玩得乐此不疲。我不禁陷入深思:为什么不把儿歌引入到口算练习中呢?
【Background】 Sujiao primary school mathematics multiplication in the second grade, runs through the entire primary school mathematics and gradual progress based on the cognitive level of students. Multiplication teaching, require students to master the arithmetic, pen calculation and calculation. However, in actual life multiplication calculation is widely used. In order to improve students’ ability to communicate, teachers will consciously arrange some exercises, but in the absence of supervision, they often can not implement it. During a class activity, I saw the female students dancing and dancing with their children’s songs, so long songs that they remember so clearly, and you chase me to play in the bored. I can not help but fall into the ponder: Why do not children’s songs into the mouth exercise?
