This Year 4 Perimeter on a Grid Teaching PPT supports children in developing their understanding of perimeter with a specific focus on rectilinear shapes. Children will learn how to calculate the perimeter of shapes where all sides meet at right angles, using squared grids to visualise and measure accurately.

The content is organised into Let’s Learn sections, where key ideas and mathematical language are clearly modelled, and Let’s Practise sections, where pupils can immediately apply what they’ve learned through short, focused tasks.

To deepen understanding, the PPT includes reasoning and problem-solving questions, giving children opportunities to apply their knowledge in different contexts.

The final slide provides links to additional resources to support this step – be sure to check them out!
