Count & Represent Objects 1–10 — Answer Key
Part A: Fill in the Missing Number
Write the missing number on each line.
1. 2, 3, 4, 5, 6.
When counting by 1s, the next number after 3 is 4.
2. The number between 3 and 5 is 4.
On the number line, 4 sits between 3 and 5.
3. 8 is 3 more than 5.
8 − 5 = 3, so 8 is 3 more than 5.
4. 6 is 4 less than 10.
10 − 6 = 4, so 6 is 4 less than 10.
5. 5, 6, 7, 8, 9, 10.
When counting by 1s, the next number after 7 is 8.
6. The number just after 7 is 8.
On the number line, the number that comes right after 7 is 8.
7. The number just before 3 is 2.
On the number line, the number that comes right before 3 is 2.
8. 7, 8, 9, 10.
When counting by 1s, the number before 8 is 7.
9. 7 is 3 more than 4.
7 − 4 = 3, so 7 is 3 more than 4.
Part B: Matching
Match each clue on the left to the correct number on the right.
1. Draw a line to match.
A group of 6 butterflies
→ 6
9
A group of 2 rabbits
→ 2
4
A group of 9 leaves
→ 9
2
A group of 4 ducks
→ 4
6
Each group matches the number that tells how many objects are in it: 6 butterflies = 6, 2 rabbits = 2, 9 leaves = 9, 4 ducks = 4.
