Ordering Numbers to 20

This is where we practise putting the numbers 11 to 20 (and 1 to 20) into the correct order and recognising which is smaller or smallest, greater or greatest and so on. We've got lots of ideas and printables to help below.

This section follows on from Ordering Numbers to 10

Hands On Activities and Ideas

  • Build towers or stacks. You will need a lot of cubes or bricks! Start with 1, then build a stack of 2, then build a stack of 3 and so on up to 20.
    • Arrange them in order, either standing each tower up next to the one before it, or (if using lego bricks or snap cubes) laying them flat on the table.
    • Discuss with your child how the stacks get taller or longer as the numbers get bigger. Introduce the words more than, less than, smaller, greater, smallest, greatest etc. We have word cards in the Resources section below that you can use.
    • Try muddling up 2 of the stacks and challenging your child to put them right.
    • Using our mix and match number cards, ask your child to place the appropriate card by each stack.
    • If you can, leave your towers and numbers out on display for a while, for reference in the following activities.
  • Counting cube printables. Using our counting cube printables, provide your child with a number of individual cubes as well as towers of ten. Encourage them to make a stack for each number from 11 to 20, or from 1 to 20. You should also suggest that they start at 20 and work down for "counting down" practice. You could also use our counting cube printables to make a big reference poster for the wall, gluing the cubes to a big piece of paper and writing the numbers above each stack or tower, or get children to work in groups to make one for their table.
  • Mix and match cards. Give your child 3 or 4 cardinal number cards and ask them to put them in order from smallest to greatest, or from greatest to smallest. Build up until they have the whole pack of 11 to 20, and then from 1 to 20.
  • Which is? Using any of our number cards or number printables, give your children 3 numbers and ask them which is greatest and which is smallest. Practise with many different number combinations.
  • Play with toys. Gather together 20 toys. You could make a traffic jam of cards, for example, or sit 20 dolls and teddies and other soft toys in a row. Number the toys with a set of our mix and match number cards. Ask questions like "Is teddy's number smaller or greater than pink rabbit's number?"
  • Play Snap Challenge! At random moments during the day, call out "Snap Challenge! Which is greater, 17 or 19?" and similar questions. Encourage your child to Snap Challenge you.
