1、二年级上册数学单元测试-4.凯蒂学艺-表内乘法（二）一、单选题1.计算3×5和5×3时，我们可以想乘法口诀( )。 A. 三三得九                                     B. 三四十二                                       C. 三五十五 2.“5×5○27”，比较大小，在○里应填的符号是（  ）A. ＞                                         B. ＜                

2、                         C. ＝                                         D. ＋3.选一选，正确的答案（1）2×3=（  ）A. 12－3                                    B. 2＋4                                    C. 2×2                                    D. 2×4（2）4×2=（  ）A. 12－3   

3、                                 B. 2＋4                                    C. 2×2                                    D. 2×4（3）3×3=（  ）A. 12－3                                    B. 2＋4                                    C. 2×2                         

4、           D. 2×4（4）5－1=（  ）A. 12－3                                    B. 2＋4                                    C. 2×2                                    D. 2×44.“20+5○4×5”，比较大小，在○里应填的符号是（  ）A. ＞                                         B. ＜         

5、                                C. ＝                                         D. －5.填上+、－、或×、÷． （1）5○5=25，○里应填（  ）A. ÷                                          B. +                                          C. ×                                         

6、 D. －（2）6○6=12，○里应填（  ）A. ÷                                          B. +                                          C. ×                                          D. －（3）5○5=0，○里应填（  ）A. ÷                                          B. +                  

7、                        C. ×                                          D. －6.积是18的算式是（  ）。A. 48-39                                    B. 9×9                                    C. 3+6                                    D. 2×97.“3+33×3”，比较大小，在里应填的符号是（  

8、）A. ＞                                         B. ＜                                         C. ＝                                         D. －二、判断题8.4×2写成加法算式可以是4+4,也可以是2+2+2+2．9.几个加数相加，可以用乘法表示比较简便。10.2×5和5×2都读作5乘2。11.一张一百能换十张二十元12.5个2相加，写成算式是5+2。三、填空题
