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.

What are 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.

This fraction is a half.

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

So 1 is the numerator and 2 is the denominator.

Two-halves make a whole.

Thirds

This fraction is a third.

It shows that 1 piece out of the 3 is coloured in.

So 1 is the numerator and 3 is the denominator.

Three 1/3 pieces make a whole piece.

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

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.

Five 1/5 pieces make a whole piece.

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

Halves

This fraction is a half.

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

So 1 is the numerator and 2 is the denominator.

Two-halves make a whole.

Thirds

This fraction is a third.

It shows that 1 piece out of the 3 is coloured in.

So 1 is the numerator and 3 is the denominator.

Three 1/3 pieces make a whole piece.

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

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

So 1 is the numerator and 5 is the denominator.

Five 1/5 pieces make a whole piece.
