## Summary - Out now!

This unit deals with measures used in mathematics including scales, 2D representations, perimeter, area and volume.  At the start of the unit estimation is considered in context, with rounding and sensible degrees of accuracy revisited (from Unit 4) and the use of inequalities to express error bounds for rounded and truncated numbers is developed. With elegant graphics to support the learning, students learn about scale drawings and bearings, using reasoning to solve contextualised problems. Plans and elevations are met, focusing on the skills needed to draw and interpret 2D representations of 3D objects.  The unit then moves on to shapes; finding the perimeter, area and volume of shapes such as triangles, trapezium, parallelogram, cuboids, prisms and composites of these shapes.  Standard formulae for area and volume are introduced and used, and these skills are applied through graded questions, reasoning and problem-solving tasks involving perimeter, area and volume.

## 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...

Students need to think and learn to reason so probing questions are a feature of every task in every lesson.

Heather Davis. Professional Development Lead, NCETM

The fact that the resources are so thorough and there is a WS and HWK for every lesson, has saved me a huge amount of planning time as there is already plenty for students to do.

Helen Webb. Science teacher, Lutterworth College
