Choose the correct addition and subtraction fact family using 6, 17, and 11.

a. | 17 - 11 = 6, 17 - 6 = 11 | ||

b. | 6 + 11 = 17, 17 - 6 = 11 | ||

c. | 15 + 8 = 7, 7 + 8 = 15 | ||

d. | 11 + 17 = 6, 11 - 6 = 17 |

The addition and subtraction fact family of 6, 17, and 11 is

6 + 11 = 17, 11 + 6 = 17, 17 - 6 = 11, and 17 - 11 = 6.

So, the correct addition and subtraction fact family using 6, 17, and 11 is 6 + 11 = 17 and 17 - 6 = 11.

Correct answer : (2)

Which is the correct addition and subtraction fact family using 19, 5, and 14?

a. | 14 + 5 = 19, 19 - 14 = 5 | ||

b. | 5 + 14 = 21, 19 - 14 = 5 | ||

c. | 5 + 19 = 14, 14 - 5 = 19 | ||

d. | 14 + 19 = 33, 19 - 5 = 14 |

The addition and subtraction fact family of 19, 5, and 14 is

5 + 14 = 19, 14 + 5 = 19, 19 - 5 = 14, and 19 - 14 = 5.

So, the correct addition and subtraction fact family using 19, 5, and 14 is 14 + 5 = 19 and 19 - 14 = 5.

Correct answer : (1)

3.

Which number sentence can be used to check your answer for 23 + 8 = 31?

a. | 31 - 23 = 9 | ||

b. | 31 - 8 = 23 | ||

c. | 23 - 8 = 31 | ||

d. | 31 + 8 = 23 |

So, the number sentence 31 - 8 = 23 can be used to check the answer for 23 + 8 = 31.

Correct answer : (2)

4.

Which number sentence is in the fact family for 24, 42, 18?

a. | 42 + 24 = 18 | ||

b. | 24 - 18 = 42 | ||

c. | 24 - 18 = 6 | ||

d. | 24 + 18 = 42 |

The addition and subtraction fact family of 24, 42, and 18 is

18 + 24 = 42, 24 + 18 = 42, 42 - 24 = 18, and 42 - 18 = 24.

So, the number sentence 24 + 18 = 42 is in the fact family for 24, 42 and 18.

Correct answer : (4)

5.

Which number sentence is not in the fact family for 15, 3, 18?

a. | 18 - 15 = 3 | ||

b. | 18 - 3 = 15 | ||

c. | 15 + 18 = 33 | ||

d. | 15 + 3 = 18 |

The addition and subtraction fact family of 15, 3, and 18 is

3 + 15 = 18, 15 + 3 = 18, 18 - 3 = 15, and 18 - 15 = 3.

So, the number sentence 15 + 18 = 33 is not in the fact family for 15, 3, and 18.

Correct answer : (3)

6.

Which multiplication fact could be used to find 49 ÷ 7?

a. | 8 × 9 = 72 | ||

b. | 7 × 7 = 49 | ||

c. | 5 × 6 = 30 | ||

d. | 49 × 7 = 343 |

[Original expression.]

49 is dividend, 7 is divisor, and 7 will be the quotient.

[49 ÷ 7 = 7.]

Dividend becomes product, divisor and quotient become factors for multiplication fact.

So, the multiplication fact for 49 ÷ 7 is 7 × 7 = 49.

Correct answer : (2)

7.

Which multiplication fact could be used to find 10 ÷ 5?

a. | 4 × 5 = 20 | ||

b. | 2 × 5 = 10 | ||

c. | 2 × 4 = 8 | ||

d. | 10 × 5 = 50 |

[Original expression.]

10 is the dividend, 5 is divisor, and 2 will be quotient.

[10 ÷ 5 = 2.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 10 ÷ 5 is 2 × 5 = 10.

Correct answer : (2)

8.

Which multiplication fact could be used to find 16 ÷ 4?

a. | 2 × 8 = 16 | ||

b. | 8 × 2 = 16 | ||

c. | 16 × 4 = 64 | ||

d. | 4 × 4 = 16 |

[Original expression.]

16 is dividend, 4 is divisor, and 4 will be the quotient.

[16 ÷ 4 = 4.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 16 ÷ 4 is 4 × 4 = 16.

Correct answer : (4)

9.

Which multiplication fact could be used to find 32 ÷ 4?

a. | 8 × 4 = 32 | ||

b. | 16 × 2 = 32 | ||

c. | 32 × 1 = 32 | ||

d. | I don′t know. |

[Original expression.]

32 is dividend, 4 is divisor, and 8 will be the quotient.

[32 ÷ 4 = 8.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 32 ÷ 4 is 8 × 4 = 32.

Correct answer : (1)

10.

Which multiplication fact could be used to find 60 ÷ 5?

a. | 15 × 4 = 60 | ||

b. | 12 × 5 = 60 | ||

c. | 10 × 6 = 60 | ||

d. | 30 × 2 = 60 |

[Original expression.]

60 is dividend, 5 is divisor, and 12 will be the quotient.

[60 ÷ 5 = 12.]

Dividend becomes product, divisor and quotient become factors for multiplication fact.

So, the multiplication fact for 60 ÷ 5 is 12 × 5 = 60.

Correct answer : (2)
