Number Bond Example: Learn Number Bond with Interactive Examples

Number bonds are pairs of numbers that are added together to form another larger number. This is why they are often referred to as number pairs. For example, a number bond looks like this: 9 + 1 = 10.

Children who are aware of number bonds can easily and speedily solve addition, subtraction, multiplication, and division problems. Also, they can immediately fill any of the three numbers, if any of them are missing, given the other two numbers.

What are Number Bonds?

A number bond is a model that represents the relationship between a number (whole) and its parts. For example, 4 + 2 = 6.

Addition and Subtraction Using Numbers Bond

Let us understand how to add and subtract using number bonds or number pairs with the help of an example below:

• 8 = 5 + 3

• 8 = 3 + 5

• 8 - 5 = 3

• 8 - 4 = 4
  
  

Multiplication and Division Using Numbers Bond

Let us understand how to multiply and divide using number bonds or number pairs with the help of an example below:

Activities to Teach Children Number Bonds at Home

Here are the different ways that you use to make your child number bond at home:

1. Give your child 10 different objects such as buttons, sweets, pens, toys, etc., and ask them the questions such as

• What do you add to 5 toys to make them 9?

• You have 10 buttons, you give 4 to your friends. How many buttons will be left will you?

• If you have 10 chocolates and you have to distribute equal chocolates among 5 of your friends, how many chocolates will each friend get?

• If a pack of pens contains 5 pens, how many pens will 2 packs contain?

2. Write a list of 10 numbers and ask your child and check how much time it takes them to look for another number that makes up each pair ( 2 and 8, 5 and 5, and 7 and 3, etc).

3. Print or draw number cards and ask your child to match them into number pairs or number bonds.
   
   

Conclusion

Thus, number bonds are pairs of numbers that are added together to make another larger number. A number bond is the easiest tool for children to learn arithmetic operations such as addition, subtraction, multiplication, and division. Encouraging children to learn number bonds up to 10 or 20 can help them to solve arithmetic calculations accurately and confidently.
