Skip Counting — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 2, 4, 6, 8, 10, 12.
This sequence counts by 2s. The missing number between 6 and 10 is 6 + 2 = 8.
2. 10, 20, 30, 40, 50.
This sequence counts by 10s. The missing number between 30 and 50 is 30 + 10 = 40.
3. 5, 10, 15, 20, 25.
This sequence counts by 5s. The missing number between 10 and 20 is 10 + 5 = 15.
4. 16, 18, 20, 22, 24.
This sequence counts by 2s. The missing number between 20 and 24 is 20 + 2 = 22.
5. 50, 60, 70, 80, 90.
This sequence counts by 10s. The next number after 80 is 80 + 10 = 90.
6. 35, 40, 45, 50, 55.
This sequence counts by 5s. The missing number between 40 and 50 is 40 + 5 = 45.
7. 110, 120, 130, 140, 150.
This sequence counts by 10s. The missing number between 120 and 140 is 120 + 10 = 130.
8. 24, 26, 28, 30, 32.
This sequence counts by 2s. The missing number between 24 and 28 is 24 + 2 = 26.
9. 75, 80, 85, 90, 95.
This sequence counts by 5s. The missing number between 85 and 95 is 85 + 5 = 90.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
2, 4, 6, 8, 10
→ Count by 2s
Count by 5s
10, 20, 30, 40
→ Count by 10s
Count by 10s from 50
5, 10, 15, 20
→ Count by 5s
Count by 2s
50, 60, 70, 80
→ Count by 10s from 50
Count by 10s
Each sequence follows a specific skip counting pattern. The difference between consecutive numbers tells you the pattern: +2 means count by 2s, +5 means count by 5s, and +10 means count by 10s.
