What your child will practise

  • Add two numbers within 20 by counting on
  • Start from the bigger number and count on the smaller one
  • Read the total from the number line

Tip for parents and teachers

Ask your child to start at the bigger number and count on the smaller one, touching each number on the line as they go. Starting from the bigger number is quicker, so 2 + 9 becomes "9, 10, 11". Small objects such as buttons or coins work well too.

How to use this worksheet

Print the question page for your child and keep the answer key for yourself. Check together, and let them correct their own mistakes.

Printing tip: choose A4 and “fit to page” in your print settings. Black-and-white printing works fine — the drawings are simple outlines that are light on ink. You are welcome to print as many copies as you need for your own children or your class; please share the link to this page rather than the file.
