Addition facts to 10
Grades 1 and 2
The 45 facts from 1 + 1 to 9 + 1 are the first ones children learn to know by heart. Once they come quickly, bigger sums get much easier.
How to learn them
- Start with the bigger number.
- Count on the smaller one.
- Doubles help: 4 + 4 is 8, so 4 + 5 is 9.
Example: 6 + 3 = ? Start at 6. Count on 3: 7, 8, 9. Answer: 9.

Questions parents ask
- When should a child know addition facts to 10?
- Most children learn them in Grade 1 and use them without counting by the middle of Grade 2. Knowing them quickly frees up attention for harder problems.
- What if my child still counts on their fingers?
- That is a normal first step. Practise a few facts at a time and try the strategies on this page, like counting on from the bigger number, so counting slowly turns into remembering.
More sets: all math facts practice. Math facts practice is not a report-card mark; it shows what a child knows by heart.
