参考答案(按天分组)
学习目标(具体考点,依据真实教材单元范围)
1.三位数乘两位数:整十/整百数乘整十数口算(30×20、160×30、400×20)、三位数乘两位数(145×12、
237×28)。
2.除数是两位数的除法:整十/几百几十除以整十数口算(80÷20、420-60、630-90,得数为整)、除法估
算(83÷20≈4)。
3.两三位数乘一位数(三年级上册复习,48×7、213×3)。
4.大数的认识:整万数加减法(50万+30万=80万)、多位数比大小(53780o62500)、整万数改写成
用“万”作单位的数(60000=6万)。
(说明:人教四年级上册无小数、无分数、无平面图形面积公式(面积仅公顷/平方千米单位)一一本册均
不出,避免超纲。)
机器承诺:全部乘除、大数加减、比大小题答案100%代码计算并经独立校验器重算复核:除法估算、整万改写为概念判断
题,建议家长抽验。
