1.

Kim had some square cards. He arranged them as shown in the figure. Which number sentence could be used to determine the total number of square cards Kim had?

a. | 4 × 3 = 12 | ||

b. | 3 × 3 = 9 | ||

c. | 6 × 3 = 18 | ||

d. | 5 × 3 = 15 |

Number of rows × Number of cards in each row = Total number of cards

5 × 3 = 15

[Substitute the values.]

So, the number sentence that could be used to determine the total number of square cards Kim had is 5 × 3 = 15.

Correct answer : (4)

2.

Choose the appropriate number sentence for the array shown.

a. | 3 × 4 = 12 | ||

b. | 4 × 4 = 16 | ||

c. | 4 × 3 = 12 | ||

d. | 3 × 3 = 9 |

Number of rows × Number of triangles in each row = Total number of triangles

3 × 3 = 9

[Substitute the values.]

So, the number sentence that represents the array shown is 3 × 3 = 9.

Correct answer : (4)

3.

How many fish are there?

a. | 4 groups of 3 = 12 | ||

b. | 3 groups of 3 = 9 | ||

c. | 6 groups of 3 =18 | ||

d. | 8 groups of 3 = 24 |

So the total number of fish is given by 4 × 3 = 12.

Correct answer : (1)

4.

How many circles are there in the figure?

a. | 5 × 7 = 33 | ||

b. | 6 × 5 = 30 | ||

c. | 6 × 4 = 24 | ||

d. | 8 × 5 = 40 |

So the total number of circles is given by 6 × 5 = 30.

Correct answer : (2)

5.

Brian gave 3 baseball cards to each of his 5 friends. Hence the total number of baseball cards that Brian gave to his friends was 3 × 5. Which one of these repeated additions represents the same?

a. | 3 + 3 + 3 | ||

b. | 3 + 3 + 3 + 3 + 3 | ||

c. | 3 + 3 + 3 + 3 | ||

d. | 5 + 5 + 5 + 5 + 5 |

[To write the multiplication fact as repeated addition.]

So, 3 + 3 + 3 + 3 + 3 is the repeated addition statement for 3 × 5.

Correct answer : (2)

6.

The picture shows groups of stars. Which number sentence tells you how many stars are there?

a. | 2 × 4 = 8 | ||

b. | 3 × 3 = 9 | ||

c. | 3 × 2 = 6 | ||

d. | 2 × 3 = 6 |

Number of rows × Number of stars in each row = Total number of stars

2 × 4 = 8

[Substitute the values.]

So, the number sentence that tells us the total number of stars in the picture is 2 × 4 = 8.

Correct answer : (1)

7.

The picture shows the way Carlos packed frog toys in a box. Which number sentence tells you the number of frog toys in the box?

a. | 2 × 3 = 6 | ||

b. | 2 × 2 = 4 | ||

c. | 2 × 7 = 14 | ||

d. | 2 × 6 = 12 |

Number of rows × Number of frog toys in each row = Total number of frog toys

2 × 7 = 14

[Substitute the values.]

So, the number sentence that tells us the total number of frog toys in the box is 2 × 7 = 14.

Correct answer : (3)

8.

Which of the given number sentences matches with the picture?

a. | 2 × 14 | ||

b. | 2 × 12 | ||

c. | 2 × 22 | ||

d. | 2 × 10 |

So the number sentence that matches the picture is 2 × 14.

Correct answer : (1)

9.

Identify the array that represents the number sentence 5 × 4.

a. | Figure 4 | ||

b. | Figure 2 | ||

c. | Figure 3 | ||

d. | Figure 1 |

Among the figures, only Figure 4 has 5 rows with 4 butterflies in each row.

So, Figure 4 is the array that represents the given number sentence 5 × 4.

Correct answer : (1)

10.

Wilma takes 3 slices of bread in her breakfast each day. Which number sentence shows the total number of slices she would have in 4 days?

a. | 3 × 1 | ||

b. | 3 × 4 | ||

c. | 3 × 3 | ||

d. | 3 + 4 |

Number of slices of bread Wilma would eat in 4 days = 3 + 3 + 3 + 3

[Add 3 repeatedly for 4 times.]

= 3 × 4

[Write the addition fact as a multiplication fact.]

So the number sentence showing the number of slices of bread Wilma would have in 4 days is 3 × 4.

Correct answer : (2)
