# Numerators(KS1, Year 2)

## The Lesson

The numerator is the number written above the line of a fraction. The numerator of this fraction is 1. (The number below the line is called the denominator. It is 4 in the fraction above.)

## Dictionary Definition

The Oxford English Dictionary defines the numerator as "the number written above the line in a vulgar fraction, showing how many of the parts indicated by the denominator are taken."

## Examples of Numerators

The numerator of the fraction 2/3 (two-thirds) is 2. The numerator of the fraction 5/7 (five-sevenths) is 5. ## What Does the Numerator Mean?

A fraction is a part of a whole number. The numerator tells you how many parts of the whole number there are. (The denominator tells you how many equal parts the whole is divided into.)

## Visualizing the Numerator

Thinking of slices of a cake is a useful way of visualizing the numerator. A fraction is a part of a whole number. So it can be visualized as a number of slices of cake, which are parts of the whole cake. The numerator tells you have many slices you have:
• A numerator of 1 represents 1 slice of cake. • A numerator of 2 represents 2 slices of cake. • A numerator of 3 represents 3 slices of cake. • A numerator of 4 represents 4 slices of cake. (The denominator tells you how many slices there are in the whole cake. There are 4 slices in the cake above, so the denominators of all the fractions shown is 4.)

## What Is a Fraction?

A fraction is a part of a whole number. Fractions consist of a numerator and a denominator. There are three different types of fractions:

## Fractions with Larger Numerators Are Larger

If fractions have the same denominator, having a larger numerator makes the fraction larger. If you visualize the numerator as the number of slices of cake, then having a larger numerator means having more slices. (If the denominator is the same, then the number of slices in a whole cake stays the same).
