Skip Counting — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Count by 2s: 0, 2, 4, 6, 8.
Counting by 2s from 0, the next number after 6 is 6 + 2 = 8.
2. Count by 5s: 0, 5, 10, 15, 20.
Counting by 5s from 0, the next number after 15 is 15 + 5 = 20.
3. Count by 10s: 0, 10, 20, 30, 40.
Counting by 10s from 0, the missing number between 20 and 40 is 20 + 10 = 30.
4. 5 + 5 + 5 + 5 = 20.
Adding four 5s together: 5 + 5 + 5 + 5 = 20. This is the same as counting by 5s four times.
5. 10 + 10 + 10 = 30.
Adding three 10s together: 10 + 10 + 10 = 30. This is the same as counting by 10s three times.
6. 2 + 2 + 2 + 2 + 2 = 10.
Adding five 2s together: 2 + 2 + 2 + 2 + 2 = 10. This is the same as counting by 2s five times.
7. Count by 5s three times from 0: 5, 10, 15.
Counting by 5s three times from 0 gives 5, 10, 15. The third number is 10 + 5 = 15.
8. Count by 10s from 60: 60, 70, 80, 90.
Counting by 10s from 60, the next number after 80 is 80 + 10 = 90.
9. Count by 2s from 18: 18, 20, 22, 24.
Counting by 2s from 18, the next number after 22 is 22 + 2 = 24.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
5 + 5 + 5 = ___
→ 15
25
2 + 2 + 2 + 2 = ___
→ 8
8
10 + 10 + 10 + 10 = ___
→ 40
40
5 + 5 + 5 + 5 + 5 = ___
→ 25
15
Each addition problem uses repeated addition, which is the same as skip counting. 5 + 5 + 5 = 15, 2 + 2 + 2 + 2 = 8, 10 + 10 + 10 + 10 = 40, and 5 + 5 + 5 + 5 + 5 = 25.
