# Introduction to fractions

### What is Fraction?

Fractions represent equal parts of a whole or a collection.

Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole.

Fraction of a collection: Fractions also represent parts of a set or collection.

### Fraction notation

A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken.  The number below the line is called the denominator.  It shows the total divisible number of equal parts the whole into or the total number of equal parts which are there in a collection.

## Real life examples

The most common examples of fractions from real life are equal slices of pizza, fruit, cake, a bar of chocolate, etc.

## Non-examples

When the parts of the whole are unevenly divided, they don’t form fractions.

Types of fractions

Unit fractions

Fractions with numerator 1 are called unit fractions.

Proper fractions

Fractions in which the numerator is less than the denominator are called proper fractions.

Improper fractions

Fractions in which the numerator is more than or equal to the denominator are called improper fractions.

Mixed fractions

Mixed fractions consist of a whole number along with a proper fraction.

A simple and fun activity for beginner students in the classroom

To play: group your students in table groups (this could be played independently but peer collaboration is my favorite!) and give each group a fraction card and several sticky notes. Hang the different fraction posters around the room (square model, circle model, rectangle model, word form, numerator, denominator). Students will work together as a table group to represent the fraction on their card in the various forms that are on the posters.  After they have it the form of their fraction on their sticky note, they stick it to the correct poster.
