2) On Tuesday, 243 people visited the zoo. On Wednesday, 152 people visited. How many people in all visited the zoo on Tuesday and Wednesday.

111

395

95

500

The total number of people who visited the zoo on Tuesday and Wednesday can be calculated by adding the number of people who visited on each day. On Tuesday, 243 people visited the zoo, and on Wednesday, 152 people visited. Adding these two numbers together gives us a total of 395 people who visited the zoo on both days.

3) What is the expanded form of this number? 8,043

8,000 + 400 + 30

80 + 40 + 30

8,000 + 40 + 3

8,000 + 400 + 3

The expanded form of the number 8,043 is obtained by breaking down the number into its place values. In this case, the number can be expressed as 8,000 (8 thousands), 40 (4 tens), and 3 (3 ones).

4) Look at the number pattern below.

19 * 21 * 23 * A * B * 29 * 31 * 33 * C Where does the number 35 belong?

A

B

C

The number 35 belongs in position C. This can be determined by observing the pattern of the numbers given. The pattern starts with 19 and increases by 2 each time, except for the missing numbers A and B. The pattern then continues with 29 and increases by 2 each time, except for the missing number C. Therefore, the missing number C must be 35.

5) Look at the number sentence below.

2 + 9 = 4 + ___

Which number makes the number sentence true?

7

11

13

15

In order for the number sentence to be true, the two sides of the equation must be equal. Since 2 + 9 is equal to 11, the other side of the equation must also equal 11. Among the given options, only 7 is equal to 11 when added to 4. Therefore, 7 is the number that makes the number sentence true.

6) Ben, Jan and Frank picked apples. They picked 11 apples in all. Ben picked 3 apples. Jan picked 5 apples. How many applies did Frank pick?

3

4

8

19

Based on the information given, Ben picked 3 apples and Jan picked 5 apples. Since the total number of apples picked by all three is 11, and we already know the number of apples picked by Ben and Jan, we can subtract their total from the overall total to find out how many apples Frank picked. Therefore, Frank picked 3 apples.

Since the total number of apples picked by all three is 11, and we already know the number of apples picked by Ben and Jan, we can subtract their total from the overall total to find out how many apples Frank picked. Therefore, Frank picked 3 apples.

7) Arlene wrote down what the other students did during recess. She put the information in the chart below.

Games Played At Recess
______________________________________________________________

Baseball        X X X X

Jump Rope    X X X

Kickball          X X

_______________________________________________________________
Each X stands for 2 students.

How many students played during recess?

27

8

9

18

Based on the chart, we can see that there are 4 X's for baseball, 2 X's for jump rope, and 2 X's for kickball. Each X represents 2 students. Therefore, for baseball, there are 4 X's * 2 students per X = 8 students. For jump rope, there are 2 X's * 2 students per X = 4 students. And for kickball, there are 2 X's * 2 students per X = 4 students. Adding up all the students, we get 8 + 4 + 4 = 16 students. Therefore, the correct answer is 18.

8) Look at the shapes below.

What fraction of the shapes are circles?

1/2

2/3

2/5

3/4

The fraction of the shapes that are circles can be determined by counting the number of circles and dividing it by the total number of shapes. Since there are 2 circles out of the total 5 shapes, the fraction of the shapes that are circles is 2/5.
