Fascinating Fact:

Three is odd. Threes jump across odd and even. 3 is odd, 6 is even, 9 is odd. Spot the pattern.

In KS1 Maths, counting in threes helps pupils spot patterns, use number lines, and build early times table facts. Every jump adds 3. Numbers alternate odd and even as you go.

  • Skip counting: Counting by a fixed step, such as 3, 6, 9, 12.
  • Number line: A line of numbers in order that you can jump along in equal steps.
  • Multiple: A number made by multiplying another number, like 3 × 4 = 12.

Practice now in the Numeracy Game to count in 3s on a number line and make quick jumps.

What does counting in threes mean for Year 2?

Counting in threes means adding 3 each time. You say 3, 6, 9, 12, 15 and so on. It prepares you for the 3 times table.

How do I use a number line to count in 3s?

Start at 0 or 3, then make equal jumps of 3 along the number line. Land on 3, 6, 9, 12 and keep going to find the next numbers.

Is 30 a multiple of 3?

Yes. 30 is a multiple of 3 because 3 × 10 = 30. When you count in 3s you will land on 30 after ten jumps from 0.
