This stimulating and comprehensive lesson enables students to use their understanding and knowledge of ratio and scale factor to solve problems involving similar shapes.
The lesson follows a step-by-step learning journey, in which children learn through:
Defining, exemplifying, and understanding the basic rules of similar shapes and enlargements through clear and simple explanations of ratios and scale factors;
Demonstrating their understanding through well-differentiated application and challenge activities;
Applying their understanding to real-life problems, in this case designing a garden using their own scale factor with a specific set of measurements;
Gauging their own understanding through both AfL activities and self-reflection tasks.
Whole lesson PowerPoint - clear and precise, colourful and comprehensive;
Bronze, Silver, and Gold level award worksheets - carefully differentiated and provided in both Word and PDF;
Teacher answer sheets;
A detailed teacher lesson plan.
There are also opportunities for group learning, speaking and listening, peer assessment, and whole class discussion. I originally used these resources with Year 6 (and higher-attaining Year 5) classes, however colleagues have used them for between years 4 and 9 with some minor adaptations. Some of the gold level challenges get really difficult, so this lesson really would also be suitable for KS3 children.
