This number bonds to 10 game helps kindergarten and first grade children learn the pairs of numbers that make 10, such as 3 + 7 and 6 + 4, by playing: pop balloons, flip memory cards, race cars or sprint through true and false sentences. Each question gives one part and asks for the missing part, like 4 + ? = 10, so children practice the make 10 facts that all later addition and subtraction depends on. It is free, needs no sign-up, works on phones and tablets, and comes with a printable number bonds chart with ten frames.
Number bonds to 10 game: see how it plays
The game below has four modes, and every question asks for the missing part of 10. The printable chart shows all eleven pairs with a ten frame for each, and the pictures show Memory Match, Balloon Pop and Answer Race on this page.




How the number bonds to 10 game works
- Answer Race: every right answer moves your car forward, and you race three computer cars to the finish flag. The first to 15 wins, and wrong taps cost time, not places.
- Balloon Pop: answers float up on balloons, and you pop the right one before it drifts off the top. The wrong balloons are within 3 of the right answer, so children have to work the missing part out and not just spot the odd number. The game speeds up as your score climbs, and three misses ends the round.
- Memory Match: twelve face-down cards hide six questions such as 8 + ? = 10 and their six answers. Flip two at a time and match each one to its answer in as few moves as you can.
- True or False: sixty seconds on the clock. Decide whether each sentence, such as 3 + ? = 10 is 7, is right or wrong. A streak of five or more scores double.
Make 10 game: all 11 number bonds to 10
A number bond splits a whole into two parts, and the whole here is 10. Counting zero and ten, there are eleven pairs, but only six are really different, because 3 + 7 is the same fact as 7 + 3. Every question in the game uses one of these pairs, and the ten frame shows the missing part as empty circles:
| Number bond | On a ten frame | Subtraction fact |
|---|---|---|
| 0 + 10 = 10 | ○○○○○○○○○○ | 10 − 0 = 10 |
| 1 + 9 = 10 | ●○○○○○○○○○ | 10 − 1 = 9 |
| 2 + 8 = 10 | ●●○○○○○○○○ | 10 − 2 = 8 |
| 3 + 7 = 10 | ●●●○○○○○○○ | 10 − 3 = 7 |
| 4 + 6 = 10 | ●●●●○○○○○○ | 10 − 4 = 6 |
| 5 + 5 = 10 | ●●●●●○○○○○ | 10 − 5 = 5 |
| 6 + 4 = 10 | ●●●●●●○○○○ | 10 − 6 = 4 |
| 7 + 3 = 10 | ●●●●●●●○○○ | 10 − 7 = 3 |
| 8 + 2 = 10 | ●●●●●●●●○○ | 10 − 8 = 2 |
| 9 + 1 = 10 | ●●●●●●●●●○ | 10 − 9 = 1 |
| 10 + 0 = 10 | ●●●●●●●●●● | 10 − 10 = 0 |
The pairs 5 + 5, 6 + 4 and 7 + 3 are the ones children need to know instantly, because the rest come from them: if 6 + 4 is 10, then 4 + 6, 10 − 4 and 10 − 6 are all known too. Playing the addition within 10 game first gives a good start, and the number bonds to 10 game then makes the pairs automatic.
Pairs that make 10 and number bonds game ideas
Every number bonds game is built on this pattern. When one part goes up by one, the other goes down by one, and the total stays 10. Children who see this pattern stop counting the missing part: if 4 + 6 is 10, then 5 + 5 is 10 and 6 + 4 is 10. The pattern also shows the “friends of ten” idea used in many classrooms, and a child who knows the friend of 7 is 3 does not need to count. Practicing the number bonds to 10 game for a few minutes a day makes this automatic.
Using number bonds to 10 to add bigger numbers
The bonds are used to bridge through ten. To add 8 + 5, take 2 from the 5 to make the 8 into 10, then add the 3 that is left. This is the main reason the bonds matter, and it works for every fact that crosses ten:
| Question | Split to make 10 | Answer |
|---|---|---|
| 8 + 5 | 8 + 2 + 3 | 10 + 3 = 13 |
| 9 + 4 | 9 + 1 + 3 | 10 + 3 = 13 |
| 7 + 6 | 7 + 3 + 3 | 10 + 3 = 13 |
| 6 + 7 | 6 + 4 + 3 | 10 + 3 = 13 |
| 9 + 8 | 9 + 1 + 7 | 10 + 7 = 17 |
| 8 + 7 | 8 + 2 + 5 | 10 + 5 = 15 |
For the full list of teen sums, practice with the addition within 20 game, and use the subtraction within 10 game for the other direction.
