Length and height - Four operations with length - Starter

The initial segment of the lesson, known as the 'Starter', introduces students to the four fundamental operations—addition, subtraction, multiplication, and division—utilised within the context of measuring length. This foundational activity is designed to engage students and prepare them for the more complex tasks ahead. By focusing on length, students apply these arithmetic operations to real-world scenarios, such as calculating the perimeter of shapes or determining the distance between two points. The Starter serves as a warm-up to refresh students' mathematical skills and ensure they are comfortable with the basic concepts of measuring and manipulating lengths before moving on to more advanced applications.

During this introductory phase, students might encounter a variety of exercises that challenge them to add, subtract, multiply, or divide lengths, which could be presented in different units of measurement. This practice not only reinforces their computational skills but also enhances their understanding of length as a measurable attribute and its practical applications. The goal is to establish a solid foundation in handling lengths mathematically, setting the stage for more in-depth exploration of geometry and measurement as the lesson progresses.
