2. 64 people went to the park for a picnic. The ice cream truck came with dessert,
but only had 52 ice cream cones. How many more ice cream cones are needed
for each person to have one for dessert?

116

16

20

Since there are 64 people at the picnic and the ice cream truck only has 52 ice cream cones, we need to find out how many more ice cream cones are needed for each person to have one. To do this, we subtract the number of ice cream cones available (52) from the number of people (64), which gives us 12. Therefore, 12 more ice cream cones are needed for each person to have one for dessert.

4. What is the expanded form of 6,450

600 + 40 + 5

6,000 + 400 + 5

6,000 + 400 + 50

6,000 + 40 + 5

The expanded form of 6,450 is 6,000 + 400 + 50.

Explanation

The expanded form of 6,450 is 6,000 + 400 + 50.

5. What is the expanded form of 3,004

300 + 40

300 + 4

3,000 + 4

3,000 + 40

The expanded form of 3,004 is obtained by breaking down the number into its place values. In this case, the number can be expressed as 3,000 + 4, where 3,000 represents the thousands place and 4 represents the units place.

6. Wendy, Tasha and Kim brought 7 cookies in all.

Wendy ate 3 cookies.
Kim ate 2 cookies.
Tasha ate the rest of the cookies.

How many cookies did Tasha eat?

2

1

5

4

12

Tasha ate the rest of the cookies, which means she ate all the remaining cookies after Wendy and Kim had their share. Since Wendy ate 3 cookies and Kim ate 2 cookies, there were 7 - 3 - 2 = 2 cookies left for Tasha to eat. Therefore, Tasha ate 2 cookies.

Explanation

Tasha ate the rest of the cookies, which means she ate all the remaining cookies after Wendy and Kim had their share. Since Wendy ate 3 cookies and Kim ate 2 cookies, there were 7 - 3 - 2 = 2 cookies left for Tasha to eat. Therefore, Tasha ate 2 cookies.

7. Look at the number pattern below.

7 * 10 * 13 * A * B * 22 * 25 * C

Where does the number 19 belong?

A

B

C

The number pattern increases by 3 each time, so the missing numbers can be found by adding 3 to the previous number. The sequence is 7, 10, 13, 16, 19, 22, 25. The number 19 belongs in the position B.

8. Look at the number sentence below.

5 + 4 = 7 + ___

Which number makes the number sentence true?

9

16

2

0

The number sentence is asking for a number that, when added to 7, will equal the sum of 5 and 4. The only option that satisfies this condition is 2.

9. Fred and Trudy went to the store to buy a book.

Fred had 20 cents. Trudy had 31 cents.
The book they wanted cost 60 cents.

Which number sentence tells the same math story?

20 + 31 + ___ = 60

60 + 20 = ___

20 + 31 + 60 = ___

20 + ___ = 31

The number sentence that tells the same math story is 20 + 31 + ___ = 60. This is because Fred had 20 cents and Trudy had 31 cents, so the sum of their amounts is represented by 20 + 31. The blank space represents the cost of the book, which is 60 cents.

Explanation

The number sentence that tells the same math story is 20 + 31 + ___ = 60. This is because Fred had 20 cents and Trudy had 31 cents, so the sum of their amounts is represented by 20 + 31. The blank space represents the cost of the book, which is 60 cents.

10. Mary and Joe watched the children on the playground.

They wrote down how many people did each playground activity.
They put the information in the chart below.

GAMES PLAYED AT RECESS
_______________________________________________

Children who slid on the slide:            X X X X

Children who jumped rope:                 X X X

Children who played on the swings:    X X X X X
________________________________________________
NOTE: Each X stands for 5 students.

How many students slid on the slide?

4

15

20

5

Mary and Joe recorded the number of children participating in different activities on the playground. Each "X" in the chart represents 5 students. In the chart, there are 4 "X's" for sliding on the slide. Since each "X" represents 5 students, multiplying 4 by 5 gives us a total of 20 students who slid on the slide. Therefore, the correct answer is 20.
