There are many videos to watch. Some of the videos have a REVISION ICON next to them. This means that you only watch these if you need to revise a concept. If you are confident that you don't need to revise the concepts, you can just go straight ahead. However, you might find that when you start the exercises, you actually do need to revise the concepts, and you can go back to the revision films then!

In this unit of work we are looking at RATIONAL NUMBERS. But what are RATIONAL NUMBERS?
RATIONAL NUMBERS are numbers that can be written as a fraction, or a RATIO of two integers. Our number system is called the REAL number system. The REAL number system contains all the RATIONAL and IRRATIONAL numbers. Yes, you guessed it. An IRRATIONAL number is a number that CANNOT be written as a fraction!
WATCH THIS VIDEO: This video clearly explains what rational and irrational numbers are, and how all the different sets of numbers (natural numbers, whole numbers, integers, rational numbers and irrational numbers) relate to each other
