You can help your child to learn the addition facts to 20.  

What you need:

Test Cards (PDF, 31KB) You can print these or make your own.

What to do:

Print out the cards and glue them to light cardboard. Cut out the cards along the solid lines and fold along the dotted lines. The folded portion is used to cover the answer. 
Only fold back the card to see if your answer is right.
Practice with a few cards at a time.

What to expect your child to do:

  • Initially children may need to use mental strategies to solve the addition facts.
  • Progress to instantly recalling the addition facts. 


  • Your child can make two piles of cards of ones they know and ones they are still learning. The cards could be stored in two separate containers.
  • Ask your child the questions orally.
  • You can cover the cards with clear 'coverseal' so that you can use felt pens to write in the answers and then wipe them clean to use again. 
  • Use your home languages to do this activity with your children.
