Skip Counting – The Path to Multiplication
Skip counting means counting forwards or backwards by a fixed amount each time. It is one of the earliest bridges between counting and multiplication.
Skip Counting in 2s
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
These are the multiples of 2. Skip counting in 2s is exactly the 2 times table.
Skip Counting in 5s
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
Skip Counting in 10s
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Why It Helps Multiplication
When you skip count, you are building the times table for that number one step at a time. Counting in 3s to reach 21 is the same as knowing 7 × 3 = 21.
| Skip counting sequence | Equivalent multiplication |
|---|---|
| 3, 6, 9, 12 (4 jumps) | 4 × 3 = 12 |
| 4, 8, 12, 16, 20 (5 jumps) | 5 × 4 = 20 |
| 6, 12, 18 (3 jumps) | 3 × 6 = 18 |
Backwards Skip Counting
Counting backwards in equal steps connects to division. 20, 15, 10, 5, 0 means 20 ÷ 5 = 4 jumps.
Key Takeaways
- Skip counting = adding the same number repeatedly.
- The nth number in a skip count of k is n × k.
- Forward skip counting builds multiplication; backward builds division.
- Spot patterns: multiples of 5 end in 0 or 5; multiples of 2 are always even.
