What is skip-counting by 5s?

Skip-counting by 5s means adding 5 each time as you count forward. Instead of saying every number one by one, you count by 5s: 0, 5, 10, 15, and so on.

Examples:
  • 0, 5, 10, 15, 20
  • 25, 30, 35, 40, 45
  • … keep going until 1,000
Note

Skip-counting helps you count faster and prepares you for learning multiplication and division.

How to identify skip-counting by 5s

You can tell numbers are being skip-counted by 5s when each number is exactly 5 more than the one before it.

Steps:
  • Start at 0.
  • Add 5 each time: 0 + 5 = 5, 5 + 5 = 10, 10 + 5 = 15.
  • Keep adding 5 to find the next number in the pattern.
Note

Look at the ones place: when you skip-count by 5s, the digits end in 0 or 5.

Why skip-counting by 5s is useful

Skip-counting by 5s is a quick way to count groups of objects, like fingers, nickels, or minutes on a clock.

Examples in real life:
  • Counting nickels: 5¢, 10¢, 15¢, 20¢…
  • Counting minutes on a clock: 5, 10, 15, 20…
  • Counting fingers by groups of 5: 5, 10, 15, 20…
Note

Skip-counting is also the foundation for learning the 5 times multiplication table.

Using skip-counting in math

You can use skip-counting to solve problems with addition, multiplication, and patterns.

Examples:
  • If there are 6 groups of 5 apples, count by 5s: 5, 10, 15, 20, 25, 30.
  • On a clock, if the big hand moves 4 times by 5 minutes, it has moved 20 minutes total.
  • If you want to find the 10th number when skip-counting by 5s, multiply: 10 × 5 = 50.
Note

Skip-counting helps you see patterns in numbers and connect addition to multiplication.
