Skip Counting
Learn to count by 2s, 5s, and 10s — a helpful shortcut for quick counting.
For Elementary Students
What is Skip Counting?
Instead of counting one by one (1, 2, 3, 4, 5...), you can skip over numbers and jump by a certain amount.
Think about it like this: If you have pairs of shoes, you don't need to count each shoe. You can count by twos: 2, 4, 6, 8, 10!
Counting by 2s
Start at 0 or 2, and add 2 each time:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
This is useful when counting things that come in pairs:
- Shoes (2 per pair)
- Eyes (2 per person)
- Wheels on a bicycle (2 wheels)
Counting by 5s
Start at 0 or 5, and add 5 each time:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
This helps when counting:
- Fingers on one hand (5 fingers)
- Nickels (each nickel = 5 cents)
- Groups of 5 pencils
Counting by 10s
Start at 0 or 10, and add 10 each time:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
This is the fastest way to count! Useful for:
- Dimes (each dime = 10 cents)
- Fingers on both hands (10 fingers)
- Boxes of 10 crayons
Why Skip Counting Helps
Skip counting makes counting faster and prepares you for multiplication later. When you skip count by 5s four times (5, 10, 15, 20), you've just solved 5 × 4 = 20!
For Junior High Students
Skip Counting as Multiplication
When you skip count, you're actually using multiplication without realizing it.
If you count by 3s six times: 3, 6, 9, 12, 15, 18
You've just calculated 3 × 6 = 18.
| Skip Count | Multiplication |
|---|---|
| Count by 2s, five times: 2, 4, 6, 8, 10 | 2 × 5 = 10 |
| Count by 4s, three times: 4, 8, 12 | 4 × 3 = 12 |
| Count by 7s, four times: 7, 14, 21, 28 | 7 × 4 = 28 |
Patterns in Skip Counting
Look for patterns:
Counting by 2s — All numbers are even (ends in 0, 2, 4, 6, or 8)
Counting by 5s — All numbers end in 0 or 5
Counting by 10s — All numbers end in 0
These patterns can help you check if you skipped correctly!
Using Skip Counting in Real Life
- Shopping: If apples cost $2 each, how much for 7 apples? Count by 2s seven times.
- Time: Minutes on a clock — count by 5s to read the minute hand.
- Money: Counting groups of coins quickly.
Practice
What number comes next? 5, 10, 15, 20, ___
Count by 2s: 2, 4, 6, 8, 10, 12, 14, ___
If you count by 10s four times starting at 10, what number do you reach?
