    主题 和孩子们一路前行4

    下午第三节课是信息课,因为没带脚套,有四位同学只得呆在教室里,担心他们没人看着,有什么事出,我拿出这四位同学的家庭作业,让他们在教室里订正。这其中,最令我感到纳闷的是王先贵同学,双休日的作业错误连连,我好生奇怪,在校的作业虽说有错误,但也不至于绝大部分全错呀。

     

     

     

     

    请他走到身边,一起检查错误,再细看他的作业,商是正确的,商之后商与除数相乘的积也是正确的,错误就在被除数减去商与除数相乘的积的结果不正确,我请他算14-8,看到他低着头,两手也躲在桌底下,我走到他的侧面,可怜的孩子——他在用手指关节作学具,慢慢的掰着计算148,我的第一反应就是“20以内的退位减,他一直没过关,计算的复杂,使他的耐心递减,从而对自己薄弱环节产生放弃思想,最后也就瞎写一通了,一会儿148等于4,一会儿148等于2,问急了,148又等于6了,完全是在瞎蒙。”内心里充满愧疚,从二年级接受这个班,早就知道他用手指帮助计算,我却一直没有采取什么措施,虽说着急时,也努力教他计算的好方法,但也就是一时兴起,根本没有帮他根治这个痼疾,以致遗留至今。必须从头再来,是教学数的分成呢,还是让他多练习20以内的退位减法呢?

     

     

     

     

    上午在教室里,我就从6的分成开始请他列举,记忆。然后又写了789的部分分成,请他补写完整。傍晚放学时,我检查他的练习本,根本没有动的痕迹,是我刺伤了他?“一年级20以内的退位减法,你没学好。赶快补一补。”我请他到我的身边来,她小声的嘀咕道,“我不去。”因为距离他不远,我听得很清楚,他不来,我只有到他那儿去,征求他的意见,“你说是把分成记一记,还是算一些20以内的退位减法?”他选择做减法,我写了20道算式,请他晚上在家完成,终于他欣然同意了。

     

     

     

     

    今天早上,看着他的特殊作业,我内心里最相知道的是,他是靠脑袋瓜心算的?还是借助手指关节完成的呢?怎样的方法又会更有效,能够帮助他快速补救前面的空缺呢?
