Key learning outcomes for this video:

• To be able to add and subtract fractions.
• To be able to multiply fractions.
• To be able to use the KEEP CHANGE FLIP method for dividing fractions.
• To be able to cancel fractions up and down and diagonally across a multiplication sign.

Cue card notes and useful reminders…

• The numerator is the top number of a fraction.
• The denominator is the bottom number of a fraction.
• The LCM of two numbers is the lowest number that appears in both the times tables of the numbers that you are considering.
• To add or subtract fractions they must have the same denominator. Once they have the same denominator, keep this denominator in your answer and only add or subtract the numerators.
• To multiply fractions:

> Multiply the numerators together to get the numerator in your answer and then multiply the denominators together to get the denominator in your answer.

> Then cancel down your answer if you can.

> If your answer is an improper fraction, change it to a proper fraction.

> Sometimes when multiplying fractions with large numbers you can cancel diagonally across the multiplication sign before multiplying.

> If the fractions in the question are mixed numbers, change them to improper fractions before you multiply.

• To divide fractions:

> Remember to use the KEEP, CHANGE, FLIP method and then continue as above for multiplying.

>If the fractions in the question are mixed numbers, change them to improper fractions before you multiply.

• A proper fraction has a numerator smaller than the denominator and is equal to a decimal less than 1.
• An improper fraction has a numerator greater than the denominator and is equal to a number greater than 1. We can change improper fractions to mixed numbers.
