**LO: To model and represent common fractions.**

**Know:**

- the structure of a fraction
- what a numerator in a fraction represents (they are the pieces of a whole)
- what a denominator in a fraction represents (they are the total pieces that make a whole)

**Understand:**

- that fractions have individual values which are less than a whole piece.

**Do:**

- I can model and represent unit fractions.

### The numerator is the top number of a fraction, it represents how many pieces out of the whole there are.

### The denominator is the bottom number of a fraction and it represents how many total pieces there are in a whole piece.

**Halves**

**Halves**

### This fraction is a half.

### It shows that 1 piece out of the 2 is coloured in.

**Quarters**

**Quarters**

### This fraction is a quarter.

### It shows that 1 piece out of the 4 is coloured in.

### So 1 is the numerator and 4 is the denominator.

### Two quarter pieces make a half and it takes four quarter pieces to make a whole.

**Fifths**

**Fifths**

### This fraction is a fifth.

### It shows that 1 piece out of the 5 is coloured in.

### So 1 is the numerator and 5 is the denominator.
