Are you aware of all number bonds? Practice all number bonds to learn how numbers are split or combined in addition.

## Game instructions for number bonds

What is a number bond? It's a fun way of showing how numbers are split and combined in addition. What other number, in addition to the given number, adds up to the whole? Each level generates up to 10 number bonds for the chosen sum. Number bonds are also called complementary numbers.

The number bonds are different each time you attempt a certain level. You must enter the correct number bond in order to proceed in the game. If you enter the wrong number, then it will be marked with a red border around the number. If it's too difficult, you can always change level by clicking the button Cancel. When you practice the number bonds in this game knowledge, your mental arithmetic is also excercised and it will be easier to count.

### Calculation of knowledge points

Each completed game level gives 1 knowledge point in Number bonds. The maximum number of points (25 knowledge points) is achieved when you pass all 25 levels. You'll get a bronze medal when you complete a level 2 times and a silver medal after 5 completed rounds. A gold medal will be received after 10 completed rounds. In Number bonds, the maximum number of collectable gold medals is 25. You only earn knowledge points for levels that has not been cleared before. A cleared level has a green background above. Even when you have completed a level, you can continue practicing at that level, but it gives you no more knowledge points.
