### What are fractions?

****Fractions are all around us! A fraction represents a part of a whole. We use fractions every time we have a slice of pizza or a piece of cake! Depending on how many slices our pizza is made of, our fractions change.

The top number in a fraction is called the numerator. The NUMERATOR represents how many parts we have. The bottom number in a fraction is called the denominator. The DENOMINATOR is the number of equal parts the whole is divided into.
