Counting to ten is a big win, but the teen numbers can feel tricky. Eleven, twelve, thirteen... they do not always sound the way they are written! This free number order activity for kids gives plenty of friendly practice with the numbers 11 to 20.

In each round, your child sees a small set of mixed-up numbers and arranges them from smallest to biggest. Rounds are short, so little learners stay happy and focused. It works well at home, in the classroom, or as a quick warm-up before a maths worksheet.

How to play

  1. Look at the numbers on the screen and read each one out loud.
  2. Find the smallest number first and place it at the start.
  3. Keep adding the next biggest number until the whole row is in order from 11 to 20.
  4. Check your answer, then press start again for a brand new round.

This activity helps children move beyond rote counting into real number sense. By ordering the numbers 11 to 20, your child learns that each number has a fixed place in the counting sequence, and begins to notice the pattern of a ten plus some ones. Children practise reading two-digit numerals, comparing which is smaller or bigger, and self-correcting when a number looks out of place. These skills support later work in addition, subtraction and place value. Try asking your child to say the row aloud afterwards, or to name the number that comes just before or just after a chosen number.

Frequently asked questions

What age is this number ordering activity for?
It suits most children aged 5 to 6, in senior kindergarten or Class 1. Younger children who already count confidently to ten can try it with a little help, and older learners can use it as a quick revision warm-up.
Why do children find teen numbers difficult?
Teen number names do not follow the written digits clearly. We say "thirteen" but write 13, which starts with a one. Ordering the numbers again and again helps children link the spoken name, the written numeral and the correct position in the sequence.
Is this activity free to use?
Yes, it is completely free and you do not need to sign up. Children can play as many rounds as they like, and each round shuffles the numbers so the practice stays fresh and useful.
How can I support my child while they play?
Sit nearby and ask gentle questions such as "Which one is smallest?" or "What comes after 16?" Let your child move the numbers themselves. A wrong try is a good moment to count together from 11 and find the right spot.
