Identifying equal parts in a whole in different contexts

Maths

In this unit pupils will explain that non-unit fractions are composed of more than one unit fraction using knowledge of unit fractions to find one whole. In the future unit pupils will use repeated addition of a unit fraction to form a non-unit fraction. They will compare non-unit fractions with the same denominator. They will add and subtract fractions with the same denominator.

In the prior unit pupils quantified the number of items in each part and connected to the unit fraction operator. They calculated the value of a part by connecting knowledge of division and division facts with finding a fraction of a quantity. In this unit pupils will explain that non-unit fractions are composed of more than one unit fraction using knowledge of unit fractions to find one whole.

Non-unit fractions

What fraction of frogs are on the lily pad?

True of false?  $$ \frac{4}{7} $$ of the shape is shaded.

Jacob works out the fraction of shapes that have an odd number of sides. What would the numerator of his fraction be? 

What is the denominator of the fraction shaded?

What is the numerator of the fraction shaded?

Jacob shades $$ \frac{5}{8} $$ of the stars. How many stars are left unshaded? 

Sofia shades $$ \frac{5}{9} $$ of the shape yellow and $$ \frac{2}{9} $$ green. The rest she shades red. How many parts does she shade red?
