Product - A product is the result of two or more numbers multiplied together.
Proper fraction - A proper fraction is a fraction where the numerator is less than the denominator.
Improper fraction - An improper fraction is a fraction where the numerator is greater than or equal to the denominator.
Mixed number - A mixed number is an improper fraction written as its integer part plus the fractional part where the fractional part is a proper fraction.

Pupils will need to be confident with converting between improper fractions and mixed numbers. As the pupils are coming into the room have a mixed number written on the board and ask them to write down as many equivalent fractions as they can.
