Skip Counting

Skip counting is counting by numbers other than 1, such as 2, 3 or 5.

Example: We skip count by 2 like this:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ...

Learning to "Skip Count" helps us:

Skip Count by 2

Learning to skip count by 2 means we can count things faster!

Try this example, who will be the winner?

images/skip-count-2.js

It is called "skip" counting because we skip over numbers:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...

Try It Yourself

Drag the marbles:

images/skip-count.js

We usually start skip counting at 0 (like 0, 2, 4, 6, ...), but we can start from any number:

3, 4, 5, 6, 7, 8, 9, 10, 11, ...

Now For Some Practice!

Let's try "Filling Out the Missing Numbers":

100-chart with the tens column highlighted to show skip counting by 10s

Skip Counting by 10s

Skip Counting by 10s is like normal counting (1, 2, 3,...) except with an extra "0":

10, 20, 30, 40, 50, 60, 70, 80, 90, 100, ...

100-chart with the fives and tens columns highlighted to show skip counting by 5s

Skip Counting by 5s

Skip Counting by 5s has a nice pattern:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, ...

This pattern can make it easier.

OK, let's get some practice:

100-chart with numbers highlighted in a diagonal pattern to show skip counting by 3s

Skip Counting by 3s and 4s

Skip Counting by 3s is:

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...

100-chart with numbers highlighted in vertical stripes to show skip counting by 4s

Skip Counting by 4s is:

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...

Skip Count Backwards!

Yes, skip counting also works backwards:

−1   Skip Counting Backwards (20 to 1) and (100 to 1)
−2   Skip Counting Backwards by 2
−5   Skip Counting Backwards by 5
−10   Skip Counting Backwards by 10

Skip Count by Bigger Numbers!

Try these for a challenge:

25   Skip Counting by 25s
50   Skip Counting by 50s
100   Skip Counting by 100s

Skip Counting is Repeated Addition

When we skip count, we are doing repeated addition, which is multiplication!

Example: 4 groups of 3

3 + 3 + 3 + 3 = 4 × 3 = 12
