一、口算。
$63 - 28 =$         $5×8 =$         $54÷7 =$
$6×2 =$         $55 - 26 =$         $44÷9 =$
$37 + 24 =$         $5×7 =$         $17÷3 =$
$2×9 =$         $43 + 18 =$         $30÷5 =$
$64 - 46 =$         $6×3 =$         $13÷2 =$
$4×7 =$         $37 + 43 =$         $35÷6 =$
$8×6 =$         $93 - 39 =$         $48÷8 =$
$24 + 42 =$         $9×7 =$         $49÷8 =$
$8×4 =$         $75 - 57 =$         $24÷6 =$
$82 - 46 =$         $3×9 =$         $38÷4 =$

$63 - 28 = 35$
$5×8 = 40$
$54÷7 = 7······5$
$6×2 = 12$
$55 - 26 = 29$
$44÷9 = 4······8$
$37 + 24 = 61$
$5×7 = 35$
$17÷3 = 5······2$
$2×9 = 18$
$43 + 18 = 61$
$30÷5 = 6$
$64 - 46 = 18$
$6×3 = 18$
$13÷2 = 6······1$
$4×7 = 28$
$37 + 43 = 80$
$35÷6 = 5······5$
$8×6 = 48$
$93 - 39 = 54$
$48÷8 = 6$
$24 + 42 = 66$
$9×7 = 63$
$49÷8 = 6······1$
$8×4 = 32$
$75 - 57 = 18$
$24÷6 = 4$
$82 - 46 = 36$
$3×9 = 27$
$38÷4 = 9······2$

二、在$◯$里填“$＞$”“$＜$”或“$=$”。
36 米$◯$36 厘米                        73 厘米 + 27 厘米$◯$1 米
1 米$◯$95 厘米                          1 米 - 1 厘米$◯$90 厘米
55 厘米$◯$56 米                        1 米 50 厘米$◯$2 米
1 米 - 50 厘米$◯$5 厘米             50 厘米$◯$1 米 - 40 厘米
86 厘米 - 28 厘米$◯$68 厘米     1 米 99 厘米$◯$2 米 3 厘米
