Count & Represent Objects 1–10 — Answer Key
Part A: Multiple Choice
Circle the correct answer for each question.
1. Which number is between 2 and 5?
A) 1
B) 6
C) 3
D) 7
C is correct because 3 is between 2 and 5 on the number line. 1 is less than 2, and both 6 and 7 are greater than 5.
2. What is 3 less than 10?
A) 6
B) 7
C) 8
D) 5
B is correct because 10 − 3 = 7. A common mistake is choosing A (6), which would be 4 less than 10.
3. Which shows 9 objects?
A) 5 flowers and 3 flowers
B) 4 flowers and 5 flowers
C) 6 flowers and 2 flowers
D) 3 flowers and 4 flowers
B is correct because 4 + 5 = 9. A student might pick A, but 5 + 3 = 8, not 9.
4. Which group has the fewest objects: 7 apples, 2 bananas, or 5 oranges?
A) 7 apples
B) 2 bananas
C) 5 oranges
D) They are all equal
B is correct because 2 is the smallest number among 7, 2, and 5. A student might confuse fewest with most and pick A (7 apples).
Part B: Fill in the Missing Number
Write the missing number on each line.
1. The number that comes right after 6 is 7.
On the number line, the number just after 6 is 7.
2. 4 more than 5 is 9.
5 + 4 = 9, so 4 more than 5 is 9.
3. Put in order from largest to smallest: 2, 8, 5. The middle number is 5.
In order from largest to smallest the numbers are 8, 5, 2, so the middle number is 5.
4. 3 less than 8 is 5.
8 − 3 = 5, so 3 less than 8 is 5.
5. The number between 4 and 6 is 5.
On the number line, 5 sits between 4 and 6.
