## Summary - Out now!

With a strong emphasis on using techniques from bar modelling to develop mastery, this unit focuses on developing skills with ratio.  Starting from the basics, the concept of ratio, its notation and the connection with fractions is developed.  Simplifying ratio, dividing in a given ratio and solving ratio problems in context are explored using procedural variation to support learning.  Direct proportion is linked to ratio and students recognise, represent and use direct proportion to solve graded questions. Ratio as a linear function is presented graphically, and students interpret the gradient and use reasoning to solve questions in context.  The unit closes with a component on scale factors and maps where the fluency of the earlier ratio work supports this application of ratio in a real-life context.

## What's included in the toolkit?

The GCSE units have been written to satisfy the specification for the Edexcel 1MA1 Maths GCSE. Each unit contains:

• PowerPoint slides for each component
• Detailed lesson plans
• Learning objectives and outcomes
• Exercise sheet activities with answers
• End-of-unit, exam-style assessment test with answers
• Other material and links to online resources

## What people say...

Lots of questions to gauge pupils understanding, great real life links with the slides, short pieces of info on each slide.

Abigail Alexander. Science teacher, Lutterworth College

This is a resource that is a wonderful support for trainee teachers. Rather than seize on worksheets of dubious quality from the Internet they can use these lessons whilst they develop their teaching skills and then gradually incorporate their own ideas when they are ready to do so.
