6
15.
What is the value of 5 times 2?
Correct Answer
A. 10
Explanation
To find the value of 5 times 2, we use multiplication:
5 × 2 = 10
Multiplication means adding the same number multiple times. Here, 5 is added twice: 5 + 5 = 10. Using a number line, we start at 0 and take two jumps of 5, landing on 10. If we group objects into sets of 5, two groups contain 10 in total. Checking with real-life examples, if a basket holds 5 apples and we take 2 baskets, we have 10 apples. This confirms the answer. Thus, the correct answer is 10.
16.
What is the sum of 10 and 5?
Correct Answer
B. 15
Explanation
To find the sum of 10 and 5, we perform addition:
10 + 5 = 15
Addition combines two numbers to get a total. If we start with 10 objects and add 5 more, we count upward: 11, 12, 13, 14, and 15. This confirms the sum as 15. Using a number line, we begin at 10 and take 5 steps forward, landing on 15. In real life, if we have 10 pencils and receive 5 more, we count them to get 15. Thus, the correct answer is 15.
17.
If you have 8 apples and give away 3, how many do you have left?
Correct Answer
A. 5
Explanation
To determine how many apples remain after giving away 3, we use subtraction:
8 - 3 = 5
Subtraction means taking away a certain amount from a total. If we start with 8 apples and remove 3, we count backward: 8, 7, 6, and 5. Checking on a number line, we begin at 8 and take 3 steps back, stopping at 5. This method ensures accuracy. Imagine you have 8 balloons and 3 fly away—you count what’s left and find 5. Thus, the correct answer is 5.
18.
What is the next number in the pattern: 2, 4, 6, __?
Correct Answer
B. 8
Explanation
To find the missing number in the pattern 2, 4, 6, ?, we analyze the sequence. The numbers increase by 2 each time:
2 + 2 = 4, 4 + 2 = 6
Following this pattern, we add 2 to 6:
6 + 2 = 8
This confirms the missing number is 8. Checking with a number line, we see even numbers appearing at equal intervals. If we arrange objects in groups of 2, we observe that after 6, the next group makes 8. This confirms that the correct answer is 8.
19.
A rectangle has how many sides?
Correct Answer
B. 4
Explanation
To determine how many sides a rectangle has, we analyze its shape. A rectangle has four straight edges, forming a closed figure. Looking at a drawing of a rectangle, we count each side: 1, 2, 3, and 4. Unlike a triangle, which has 3 sides, or a pentagon, which has 5, a rectangle always has 4. In real life, doors, books, and phone screens are often rectangular, and all have 4 sides. Tracing its outline confirms this. Thus, the correct answer is 4.
20.
If a box contains 6 pencils and you add 4 more, how many pencils are there?
Correct Answer
C. 10
Explanation
To find the total number of pencils after adding 4 to 6, we perform addition:
6 + 4 = 10
Adding means combining values to get a total. Counting from 6 and adding 4 more gives: 7, 8, 9, and 10. Checking with objects, placing 6 pencils in one pile and adding 4 more confirms that there are now 10. Using a number line, we start at 6 and move 4 steps forward, reaching 10. This process proves that the correct answer is 10.
21.
Which number is greater than 20?
Correct Answer
C. 25
Explanation
To find the greatest number among 15, 20, 19, and 25, we compare their values. The numbers are 15, 19, 20, and 25. Checking pairwise: 15 < 20, 19 < 20, 12 < 20, but 25 is greater than all. Listing them in ascending order, we get: 15, 19, 20, 25. The highest number in this list is 25. If we visualize these as stacks of blocks, the tallest stack belongs to 25. Thus, the greatest number is 25.
22.
What is the difference between 18 and 9?
Correct Answer
C. 9
Explanation
To find the difference between 18 and 9, we use subtraction:
18 - 9 = 9
Subtraction removes a smaller number from a larger one. If we have 18 objects and take away 9, we count down from 18: 17, 16, 15, 14, 13, 12, 11, 10, and 9. Checking with a number line, starting at 18 and moving 9 steps back lands us at 9. Splitting a group of 18 items into two equal halves also shows that each contains 9. Thus, the correct answer is 9.
23.
How many legs do 3 dogs have in total?
Correct Answer
C. 12
Explanation
To find the total number of legs for 3 dogs, we use multiplication:
3 × 4 = 12
Each dog has 4 legs, so we add 4 three times: 4 + 4 + 4 = 12. Using multiplication, 3 groups of 4 equal 12. Checking with real-life objects, if 1 dog has 4 legs and another has 4 more, we reach 8, and adding a third dog brings the total to 12. Counting each leg confirms this. Thus, the correct answer is 12.
24.
If 1 week has 7 days, how many days are there in 2 weeks?
Correct Answer
C. 14
Explanation
To determine how many days are in 2 weeks, we multiply:
7 × 2 = 14
A week has 7 days. If we consider one week as Monday to Sunday and then another, we count: Monday to Sunday (7), then another Monday to Sunday (7), totaling 14. If we add 7 two times: 7 + 7 = 14, we confirm this. Using a calendar, marking two full weeks and counting the days confirms there are 14 days. Thus, the correct answer is 14.
25.
What is half of 16?
Correct Answer
A. 8
Explanation
To find half of 16, we divide by 2:
16 ÷ 2 = 8
Dividing 16 into 2 equal parts means each part contains 8. If we split 16 apples into 2 baskets, each gets 8. Counting by twos: 2, 4, 6, 8, 10, 12, 14, 16, we see 8 is exactly halfway. Using a number line and marking the middle confirms this. Thus, the correct answer is 8.
