Count & Represent Objects 1–10 — Answer Key
Part A: Multiple Choice
Circle the correct answer for each question.
1. You have 5 apples. You get 2 more. How many apples do you have now?
A) 5
B) 6
C) 7
D) 8
5 + 2 = 7. You start with 5 apples and add 2 more to get 7 total.
2. Which group has more: 8 stars or 6 stars?
A) 6 stars
B) 8 stars
C) They are the same
D) Neither
8 stars is more than 6 stars. 8 is a larger number than 6.
3. If you count 9 flowers, what is the last number you say?
A) 8
B) 10
C) 9
D) 1
The last number you say is 9. This principle is called cardinality — the last counting number tells the total.
4. Which number is one less than 7?
A) 8
B) 5
C) 7
D) 6
One less than 7 is 6. The number before 7 on the number line is 6.
Part B: Fill in the Missing Number
Write the missing number on each line.
1. You have 3 cats. Your friend has 3 more cats. Together you have 6 cats.
3 + 3 = 6. Together you have 6 cats.
2. There are 10 birds on a branch. 4 fly away. Now there are 6 birds.
10 - 4 = 6. After 4 birds fly away, 6 remain.
3. A group of 7 balls and a group of 3 balls. There are 4 more balls in the bigger group.
7 - 3 = 4. The group of 7 has 4 more balls than the group of 3.
4. The number that is 2 more than 6 is 8.
6 + 2 = 8. Two more than 6 is 8.
5. Count by ones: 4, 5, 6, 7, 8, 9, 10.
The missing numbers are 7 (between 6 and 8) and 10 (after 9). The sequence counts by ones.
