# Constructive proof facts for kids

In mathematics, a **constructive proof** is a method of proof that shows the existence of a mathematical objectâ€”by giving a method on how to create the object. The other type of proof is called non-constructive proof, or existence proof: It shows that an object must exist, but does not give a way how to construct it.

A non-constructive proof is rejected by the so-called constructivists, who choose to interpret existence in a stricter way.
