Morning Bats. Our maths lessons this week focus on ratio, proportion and scale factor. This is something we worked  on a little before school closed so it is really important you watch the videos carefully and have a really good go at the activities. 

 

Before you begin the main part of the lesson, start by warming your brain up with one of the arithmetic slides below.

Today, we are starting by looking at what ratio means and the symbol use for ratio. 

A ratio shows how much of one thing there is compared with another. The symbol is used to compare the parts.

 

Start by watching the BBC Bitesize video below about ratio. 

 

Watch the video below which introduces ratio and the symbol use to show it.

Today's lesson is about scale factors. A scale factor is a number which scales or multiplies a quantity so it tells you how much larger something needs to be. They are used to create maps and other scale diagrams.
