Practice skip counting with fives

Math - Grade K-1

Instructions: Read each problem carefully. Count by 5s. Write your answer on the line.
  1. 1

    Fill in the missing number: 5, 10, 15, __, 25.

    Add 5 to 15.

    The missing number is 20 because 15 plus 5 equals 20.
  2. 2

    Count by 5s from 5 to 50. Write all the numbers.

    The numbers are 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50.
  3. 3

    What number comes after 25 when you count by 5s?

    Add 5 to 25.

    The number after 25 is 30 because 25 plus 5 equals 30.
  4. 4

    What number comes before 40 when you count by 5s?

    The number before 40 is 35 because 35 plus 5 equals 40.
  5. 5

    Fill in the missing numbers: 10, 15, __, 25, __, 35.

    Each number is 5 more than the number before it.

    The missing numbers are 20 and 30 because the pattern goes up by 5 each time.
  6. 6

    There are 5 apples in each basket. Count the apples in 4 baskets by 5s.

    There are 20 apples in all because 5, 10, 15, 20 counts 4 groups of 5.
  7. 7

    Circle the number that belongs in the counting by 5s pattern: 5, 10, 15, 20, 24, 25.

    Look for the number that is not 5 more than the number before it.

    The number 24 does not belong because counting by 5s goes from 20 to 25.
  8. 8

    Fill in the missing number: 30, 35, 40, __, 50.

    The missing number is 45 because 40 plus 5 equals 45.
  9. 9

    Start at 0 and count by 5s to 25. Write the numbers.

    Keep adding 5 until you reach 25.

    The numbers are 0, 5, 10, 15, 20, and 25.
  10. 10

    A hand has 5 fingers. Count the fingers on 6 hands by 5s.

    There are 30 fingers on 6 hands because 5, 10, 15, 20, 25, 30 counts 6 groups of 5.
  11. 11

    Write the next three numbers: 15, 20, 25, __, __, __.

    Add 5 again and again.

    The next three numbers are 30, 35, and 40 because the pattern adds 5 each time.
  12. 12

    Which number is 5 more than 45?

    The number 5 more than 45 is 50 because 45 plus 5 equals 50.
  13. 13

    Fill in the missing numbers on this path: 5, __, 15, __, 25, __, 35.

    Say the counting by 5s pattern out loud.

    The missing numbers are 10, 20, and 30 because the path counts by 5s.
  14. 14

    Count by 5s. Is 32 in the pattern from 5 to 50?

    No, 32 is not in the pattern because counting by 5s gives 30 and then 35.
  15. 15

    Write the numbers from 50 back to 5 counting backward by 5s.

    Take away 5 each time.

    The numbers are 50, 45, 40, 35, 30, 25, 20, 15, 10, and 5.
