Year 5 Knowledge Organiser: Perimeter and Area

This Knowledge Organiser is designed to help Year 5 students confidently calculate and understand the perimeter and area of various shapes. It provides clear, step-by-step explanations for finding the perimeter of rectangles, squares, and irregular shapes by adding the lengths of their sides. The organiser also covers the area of rectangles and squares, with formulas and real-life examples to demonstrate how to calculate area using length and width. In addition, students will learn how to apply these concepts to more complex shapes, including compound shapes, by breaking them down into smaller, manageable parts. Visual aids, example problems, and tips for solving perimeter and area challenges make this organiser an invaluable tool for reinforcing these important measurement skills, helping students approach problem-solving with confidence.
