Ioan describes how to write fractions in this previous post on Star Wars Fractions.

In it, he explains that the top number is called the numerator. The numerator is the number of equal parts we have.

The denominator is the bottom number and it shows the total number of parts the whole is divided in to.

Defining what mixed and improper fractions are.

A mixed number is made up of a whole number and a fraction. For example: 1 and 2/10.

An improper fraction is one that is ‘top-heavy’ so the numerator is bigger than the denominator. For example: 12/10.

Identifying mixed and improper fractions

Ordering fractions

Converting an improper fraction to a mixed fraction

Comparing improper fractions with the same numerator

“If my numerator is always 12, will I always have the same fraction?”

Finny was working out how many ‘wholes’ different improper fractions could be worth, even with the same numerator.

Do fractions equivalent to one half have even numerators?

If a fraction is equivalent to one half, the denominator is double the numerator. True or false.
