Common Uses of Halves Quarters and Eighths of Shapes (2)

Recognise and interpret common uses of halves, quarters and eighths of shapes and collections (ACMNA033)

LO:

To model and represent common uses of halves, quarters and eighths

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 can be used in everyday life.

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 here are.

The denominator is the bottom number of a fraction and it represents how many pieces the whole is broken into.

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.

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 4 quarter pieces to make a whole.

Eighths

This fraction is an eighth.

It shows that 1 piece out of the 8 is coloured in.

So 1 is the numerator and 8 is the denominator.

Eight 1/8 pieces make a whole piece.
