Fascinating Fact:

Real life uses tens everywhere: 10 crayons in a box, 20 playground steps, 30 pages in a mini book.

In KS1 Maths, counting in tens builds strong number sense. Children group items into tens bundles, jump along a number line by 10, and meet real-life examples like 10p coins and ten-frame patterns.

  • Tens: Groups of ten ones, used for quick counting: 10, 20, 30, and so on.
  • Place value: How the position of a digit shows its value, like the tens digit in 47.
  • Multiple of ten: A number you get by multiplying 10, such as 20, 40, or 90.
How do I teach counting in tens to Year 1?

Start with bundles of ten straws or sticks. Count 10, 20, 30 while jumping on a number line. Say the pattern together and clap on each ten.

Why do numbers end in 0 when counting in tens?

Every step adds ten, so the ones digit stays 0. This repeating pattern helps children quickly spot 10, 20, 30, 40, and so on.

How does counting in tens help with money?

Coins like 10p can be counted by tens: 10p, 20p, 30p. This makes adding prices and finding totals faster and more accurate.
