Math: Creating and Extending Number Patterns

Practice counting forward and finding what comes next

Math - Grade K-1

Instructions: Read each number pattern. Write the missing number or numbers. Show your counting in the space provided.
  1. 1

    Fill in the missing number: 1, 2, 3, __, 5

    Count by ones from 1.

    The missing number is 4 because the pattern counts up by 1 each time.
  2. 2

    What number comes next? 6, 7, 8, 9, __

    The next number is 10 because the pattern counts up by 1 each time.
  3. 3

    Fill in the two missing numbers: 2, 4, 6, __, __

    Say the even numbers in order.

    The missing numbers are 8 and 10 because the pattern counts by 2s.
  4. 4

    What number comes next? 5, 10, 15, __

    Count by fives on your fingers.

    The next number is 20 because the pattern counts by 5s.
  5. 5

    Fill in the missing number: 10, 9, 8, __, 6

    The missing number is 7 because the pattern counts back by 1 each time.
  6. 6

    Look at the pattern: 3, 4, 5, 6. Write the next two numbers.

    Keep counting after 6.

    The next two numbers are 7 and 8 because the pattern counts up by 1.
  7. 7

    A number train shows 1, 3, 5, 7. What number should go in the next train car?

    The next number should be 9 because the pattern counts by 2s.
  8. 8

    Fill in the missing numbers: 0, 2, 4, __, 8, __

    Each number is 2 more than the number before it.

    The missing numbers are 6 and 10 because the pattern counts by 2s.
  9. 9

    What number comes next? 12, 11, 10, 9, __

    The next number is 8 because the pattern counts back by 1.
  10. 10

    Create a number pattern that starts at 1 and counts up by 1. Write five numbers.

    Start with 1, then say the next number each time.

    One correct pattern is 1, 2, 3, 4, 5 because each number is 1 more than the last number.
  11. 11

    Look at the stars. The groups have 2 stars, 4 stars, and 6 stars. How many stars should be in the next group?

    The next group should have 8 stars because the pattern adds 2 stars each time.
  12. 12

    Fill in the missing number: 5, 6, __, 8, 9

    Count from 5 to 9.

    The missing number is 7 because the pattern counts up by 1 each time.
  13. 13

    What number comes next in the hop pattern? 0, 5, 10, 15, __

    The next number is 20 because the pattern counts by 5s.
  14. 14

    Circle the pattern that counts by 2s: 1, 2, 3, 4 or 2, 4, 6, 8.

    A count-by-2 pattern skips one number each time.

    The pattern 2, 4, 6, 8 counts by 2s because each number is 2 more than the number before it.
  15. 15

    Finish the pattern on the number cards: 4, 5, 6, __, __

    The missing numbers are 7 and 8 because the pattern counts up by 1.
