成人快手

Video summary

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 梅 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 成人快手 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 鈥榙ifference鈥 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?

Answer to the final question:900 divided by 24 = 37.5, so they can sell 37 full boxes.685 divided by 24 = 28.54, so they would need 29 boxes to transport all the eggs.

Following on from the film:

  • Explore the difference between rounding up and rounding down problems, as in Hypatia鈥檚 final question.
  • Look at a number, e.g. 1728. You have three lives. Each time you divide it and you get an answer with a remainder you lose a life. Which divisors will you choose and why? E.g. I鈥檒l choose 3 because 1728 has a digit total of 18 so is a multiple of 3. I鈥檒l choose 2 because it鈥檚 even. I鈥檒l choose 4 because 1700 is a multiple of 100 and therefore a multiple of 4, and 28 is a multiple of 4, etc.

This short film is suitable for teaching maths at KS2 in England, Wales and Northern Ireland and 2nd Level in Scotland.
