2019年四年级上学期同步奥数第七讲有余数的除法

一、基础夯实

1、先计算，再找出每组题的联系

96÷3＝ 86÷4＝ 47÷2＝

32×3＝ 21×4＋2＝ 23×2＋1＝

2、一个数除以5，商是123，余数是3，这个数是多少？

3、国庆节到了，学校要在6条走廊上挂彩灯，已知每条走廊上挂的彩灯一样多，且彩灯的总数是最大的两位数，挂完后还多出3盏，问每条走廊上挂了几盏彩灯？

二、新知解答

算式□÷6＝□……□中，不告诉你被除数，商是多少，你能实现了它的余数是哪几个吗？

算式□÷9＝5……□中，被除数最大是几？最小是几？

算式□÷□＝13……8中，除数最小是几？被除数最小是几？

23÷□＝□……5中，除数和商各是多少？

三、实战演练

1、下面算式中的余数可能是几？

□÷5＝□……□ ( )

□÷6＝□……□ ( )

□÷7＝□……□ ( )

2、下列算式中，余数最大是几？最小是几？

( )÷12＝( )……( ) 最大是： 最小是：

( )÷10＝( )……( ) 最大是： 最小是

( )÷12＝( )……( ) 最大是： 最小是：

3、下列算式中被除数最大是几？

( )÷3＝10……( ) ( )÷6＝5……( )

( )÷7＝8……( )

4、下列算式中除数最小是几？被除数最小是几？

( )÷( )＝7……7 除数最小是： 被除数是小是：

( )÷( )＝8……5除数最小是： 被除数是小是：

5、要使余数最大，被除数是几？

( )÷6＝7……( ) ( )÷8＝6……( )

( )÷4＝8……( )

6、下列算式中，除数和商分别是多少？

16÷( )＝( )……7 ( )÷8＝( )……( )

7、算式( )÷( )＝8……8中，除数最小是多少？被除数最小是多少？

8、下列算式中，余数和商相同，被除数有多少个？

( )÷5＝( )……( ) 被除数是( )个

( )÷6＝( )……( ) 被除数是( )个

( )÷7＝( )……( ) 被除数是( )个

( )÷8＝( )……( ) 被除数是( )个

四、挑战新高

1、从100里连续减去多少个6，最后还剩4？

2、有一堆围棋子，按“二黑三白”排列起来●●○○○●●○○○……，想一想，第21棋子是白子还是黑子？第53个棋子是白子还是黑子？
