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

 

• use concrete materials to model a half, a quarter or an eighth of a whole object, eg divide a piece of ribbon into quarters

 

 

 

    * create quarters by halving one-half, eg 'I halved my paper then halved it again and now I have quarters' (Communicating, Problem Solving)

 

    * describe the equal parts of a whole object, eg 'I folded my paper into eight equal parts and now I have eighths' (Communicating)

    * discuss why 1/8 is less than 1/4 , eg if a cake is shared among eight people, the slices are smaller than if the cake is shared among four people (Communicating, Reasoning)

• recognise that fractions refer to equal parts of a whole, eg all four quarters of an object are the same size

    * visualise fractions that are equal parts of a whole, eg 'Imagine where you would cut the rectangle before cutting it' (Problem Solving)
