Practice that grows with your child
The set begins with friendly addition sums and visual prompts, then moves towards number sentences with less support. Younger children can count pictures, objects or dots before writing the answer. Children who are ready for more can solve missing-number sums, mixed equations and simple fact families. The activities keep the focus on totals up to 20, so your child can practise one useful range without facing large numbers too soon. For an easier starting point, try Addition Within 10.
Simple ways to use the worksheets
At home, choose one sheet after a short hands-on activity. Give your child buttons, bottle caps or pencils to join two groups, then let them record the matching sum. In class, use a worksheet for independent work after a maths lesson, or place copies at a small-group table. Children can compare two different ways to make the same total, such as 8 + 4 and 6 + 6. Read each sum aloud and ask your child to explain how they found the answer rather than rushing through every question.
Help with the tricky parts
Children often count every object from one instead of starting with the larger number. Show them how to say the larger number first and count on, such as 9, 10, 11, 12 for 9 + 3. Reversing the numbers can also cause hesitation, so use counters to show that 4 + 7 and 7 + 4 make the same total. If an answer is wrong, cover part of the page and rebuild the two groups slowly. Keep number writing clear, especially when 1 and 7 or 6 and 9 look similar.
Lumi's tips
- Make it easier by covering some questions and using counters or fingers to build each pair of numbers.
- Make it harder by asking your child to write a related subtraction fact for each addition sum.
- Link the skill to real life by adding fruit pieces, toy cars or coins and recording totals up to 20.

Questions parents ask
What does addition within 20 mean?
It means adding two or more numbers when the answer is 20 or less. Examples include 7 + 5 = 12 and 9 + 9 = 18.
Which children can use these worksheets?
They suit children aged about 4 to 8, depending on their experience with counting and early addition. Younger children may need objects or picture clues, while older children can work with number sentences independently.
How can I teach addition within 20 at home?
Start with real objects such as blocks or bottle caps. Make two groups, join them, count the total and then write the matching addition sum.
What should I do if my child counts every object again?
Let your child use objects at first, then model counting on from the larger number. For 8 + 3, say 8, then count 9, 10, 11.
