二、我会算
1、我会直接写得数(10点)
12 - 9 = 11 - 7 = 16 + 8 = 17 + 80 = 47 - 7 =
15 + 30= 20 + 54 = 37 - 30 = 37 + 7 = 6 + 74 =
2、我会计算(20点)
17 - 2 + 9 = 30 + 9 + 2 = 9 + 4 + 7 = 3 + 19 - 9 =
2 + 7 + 5 = 7 + 8 - 4 = 6 + 13 + 3= 6 - 5 + 29 =
13 -7 + 10 = 13 - 8 + 8=
三、我会解决问题、(30点)
1、一共有兔子65只,白兔有20只,黑兔有多少只?
2、今天我收了7棵白菜,14个萝卜。萝卜比白菜多几个?
