What is skip-counting?

Skip-counting means counting forward or backward by a number other than one. Instead of saying every number in order, you โ€œskipโ€ some numbers each time.

Examples:
  • Counting by 2s: 2, 4, 6, 8, 10
  • Counting by 5s: 5, 10, 15, 20, 25
  • Counting by 10s: 10, 20, 30, 40, 50
Note

Skip-counting helps you find number patterns and prepares you for multiplication facts.

How to identify skip-counting patterns

A skip-counting pattern has equal spaces between each number. Look at the difference between numbers to figure out the rule.

Steps:
  • Start with the first number (example: 3).
  • Look at the next number (6).
  • Find the difference (6 โˆ’ 3 = 3).
  • The rule is โ€œcount by 3s.โ€
  • Pattern: 3, 6, 9, 12, 15...
Note

If the difference between numbers is always the same, you have found a skip-counting pattern.

Common skip-counting patterns

Here are some skip-counting patterns you will often use in math:

Patterns:
  • By 2s: 2, 4, 6, 8, 10...
  • By 3s: 3, 6, 9, 12, 15...
  • By 5s: 5, 10, 15, 20, 25...
  • By 10s: 10, 20, 30, 40, 50...
  • By 100s: 100, 200, 300, 400...
Note

Skip-counting by 5s, 10s, and 100s connects directly to place value and helps with adding and multiplying quickly.

Skip-counting and multiplication

Skip-counting is another way to think about multiplication. Each number in the pattern is a multiple of the counting number.

Examples:
  • Counting by 2s: 2, 4, 6, 8 (2 ร— 1, 2 ร— 2, 2 ร— 3, 2 ร— 4)
  • Counting by 3s: 3, 6, 9, 12 (3 ร— 1, 3 ร— 2, 3 ร— 3, 3 ร— 4)
  • Counting by 5s: 5, 10, 15, 20 (5 ร— 1, 5 ร— 2, 5 ร— 3, 5 ร— 4)
Note

Practicing skip-counting helps you learn multiplication tables faster and makes solving problems easier.

Using skip-counting in real life

Skip-counting is useful in many everyday situations, such as counting money, telling time, or grouping objects.

Examples:
  • Counting nickels: 5, 10, 15, 20...
  • Counting dimes: 10, 20, 30, 40...
  • Counting hours on a clock by 5s: 5, 10, 15, 20...
Note

Recognizing patterns in numbers helps you solve problems faster in both school and daily life.
