# Maths KS2: Dividing using written methods

Olivia and Hassan learn how to perform long division in order to free gridlocked traffic on a bridge.

Our great mathemagician Hypatia challenges them with a division question: 432 ÷ 12, and Archimedes demonstrates how they can use the method of dividing the cars as a springboard to apply long division.

The episode ends with Archimedes performing a long division question, and asking pupils to spot his mistakes.

This short animated film is from the BBC Teach series, Hypatia's Mathematical Maze.

### Teacher Notes

Before watching the film

Prior to this lesson you may wish to introduce pupils to other relevant topics, for example:

• Factors and multiples
• Mental division as the inverse of times tables
• The term ‘difference’ as a means of subtracting

During watching the film

Depending on the focus of your lesson, you may wish to pause the film at certain points and check for understanding, asking questions such as:

• What is the multiple just below one of the ones on the side of the truck in the video?
• What is the difference between the multiple found and the actual number?
• What resources could we use to find the multiples and the difference?

Final question:
A farmer sells eggs in boxes of 24. How many full boxes can he sell if he has 900 eggs? How many boxes does he need to transport all of his 685 eggs?
