Number Bonds

What Are Number Bonds?

Number bonds are pairs of numbers that add up to the same total.
For example, 2 + 3 = 5 and 4 + 1 = 5.
The total (5) is called the Sum.
You can think of a number bond like a puzzle: two pieces fit together to make a whole.

How to Find Them

1. Choose a number you want to reach, like 10.
2. Pick one number that is smaller than 10, such as 6.
3. Subtract: 10 − 6 = 4.
4. The pair 6 + 4 makes the number bond for 10.

Try it with 8, 7, or any number you like!

Fun Practice

• Clap The Bond: Say a number (e.g., 5). Clap once for the first part, twice for the second part, until the claps equal the total.
• Draw A Bond: Draw a circle, write the sum inside, and draw two lines to the numbers that make it.

Number bonds help you add quickly and make math feel like a game!
