What are Number Bonds in Math and how are they used?

[steve smith]

I’ve heard teachers mention number bonds in early math lessons. Can someone explain what number bonds are and give a simple example?

Number bonds in math show how numbers can be split or combined. For example, 5 can be broken into 2 and 3. They help children understand addition and subtraction by visualizing part-whole relationships. Used in early math education, number bonds build strong mental math skills and form the foundation for more advanced arithmetic concepts later on.

Number bonds show how a whole number can be split into two or more parts. They help students understand addition, subtraction, and part–whole relationships. By visualizing numbers this way, children build mental-math skills, learn fact families, and see how different combinations form the same total, strengthening foundational arithmetic understanding.

A whole number can be divided into two or more parts using number bonds. They aid pupils in comprehending part-whole connections, addition, and subtraction. Children learn fact families, develop mental math skills, and increase their basic comprehension of arithmetic by picturing numbers in this way.
