Applying Scaling | Ratio & Proportion | Lesson Notes, Slides & Activities

Scaling, Ratio & Proportion | Whole Unit | Lesson Notes, Slides & Activities

This purposeful unit for **scaling, ratio & proportion** includes 5 lessons, and embeds real life scenarios throughout: **Lesson 1** - explores how to keep shapes similar by enlarging or reducing by the same multiplier. **Lesson 2** - focuses on how to apply scale factors to create similar shapes, both on and off coordinate grids. **Lesson 3** - explores how to interpret and create scale drawings through designing blueprints for parks and client bedrooms. **Lesson 4** - focuses on scaling recipes and currencies for hotel guests for consistency. **Lesson 5** - focuses on using and applying ratio and proportion by scaling down the wonders of the world for a pocket museum. **Knowledge:** I know that similarity in geometry means shapes have identical angles and their sides are changed by the same multiplier. I know that a scale factor describes how much an object has been enlarged or reduced. I know that proportion involves two ratios that are equivalent, maintaining the same relationship regardless of scale. **Skills:** I can identify similar shapes by calculating the ratio between their corresponding sides. I can use a scale factor to draw an enlargement of a shape on a grid. I can apply proportional reasoning to adjust measurements. **What’s Included?** Your download includes everything you need for a successful series of lessons: **Unit Overview Notes:** Outlines the knowledge, skills, and pre-requisites for the entire unit, exploring the question 'Can bigger ever be the same?' **Detailed Lesson Walkthrough/Notes:** Includes a step-by-step guide with guiding questions and key discussion points for each lesson. **Guiding Questions:** Great opportunities for AfL throughout each lesson, designed to help your students draw on their previous learning and make purposeful connections across the unit. **Lesson Slides:** Engaging slides to guide each of your lessons. **Lesson Activities:** Includes accessible, low-floor high ceiling activities for each lesson that all students can access through adaptive teaching, leading to improved confidence.
