资源描述

1小蝌蚪的成长1.计算减法时,要( )对齐,从 ( )位减起,哪一位不够减,就从前一位退 ( ) ,在本位上加( )再减。2.计算30065 时,可以先把 65 分成( )和( ) ,200( )( )( ) ;也可以先把 300 减去( ) ,变成一个不退位的减法,再把得数加上 1。3.我是小法官。(对的画“” ,错的画“”) (1)无论计算加法还是减法,都要从高位算起。( )(2)计算加法时要把相同数位对齐,计算减法时可以不用对齐数位。( )(3)比 232 少 46 的数是多少,列式是 23246。 ( )4.用竖式计算。14957 325157544265 500274356178 843356215169 4322465.我是森林小医生。(判断,并改正)、兴华超市新进水果 531 箱,卖出 465 箱,还剩多少箱没有卖出?、学校新购进一批图书,科技书有 215 本,文艺书有 178 本,故事书有 300 本。(1)科技书比文艺书多多少本?(2)你还能提出一个用减法计算的问题吗?并尝试解答。答案与解析2略
