Skip Counting by 3s

Skip Counting by 3s

Skip counting by 3s means adding 3 each time you move to the next number in the sequence. The numbers you get are multiples of 3.

1) Look at the starting number

Find the number where the sequence begins. That is your first step.

2) Add 3 each time

To complete the sequence, keep increasing by 3:

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

If the sequence has blanks, fill each blank with the next number that is 3 more than the previous one.

3) Check the pattern

A good check is to see whether each number is 3 more than the one before it. You can also count by threes aloud or use your fingers to keep track.

4) Watch for consistency

Every term should fit the same pattern. If one number breaks the jump-by-3 rule, recheck the sequence from the start.

Quick check

After filling in the blanks, read the full sequence from left to right and verify that the difference between neighboring terms is always 3.
