For students aiming for grades 4 or 5, the ability to translate real-world problems into mathematical equations is essential. Teachers should emphasise the process of understanding the problem, clearly defining variables, and then constructing and solving equations.

Practice with a variety of contexts can build confidence and versatility. Additionally, teachers can use probing questions to ensure students are not only able to find the solution but also understand the underlying mathematical concepts.

These four examples show how to setup and solve linear equations from real-life problems. They build students’ confidence and skill, preparing them for similar exam questions.

**Key Skills:**Decomposing a shape into simpler parts, calculating areas of rectangles, and understanding how to form and solve equations.**Advice:**Practice breaking down complex figures and remember that the sum of the areas of the parts equals the area of the whole.**Check Questions:**“How did you divide the shape?” “What equation represents the total area?”

**Key Skills:**Using the concept of the mean to set up an equation that balances two sets of numbers.**Advice:**Ensure understanding of how the mean is calculated and how it relates to the sum of the numbers.**Check Questions:**“What does the mean represent?” “How can we express the mean as an equation?”

**Key Skills:**Formulating algebraic expressions to represent quantities and solving for unknowns within probability scenarios.**Advice:**Strengthen algebraic manipulation and understand probability principles, like the total number of outcomes.**Check Questions:**“What do the expressions for each box represent?” “How do you calculate the total probability?”

**Key Skills:**Setting up and solving linear equations from word problems involving proportional reasoning.**Advice:**Focus on converting the written problem into mathematical statements and solve systematically.**Check Questions:**“How do you represent the problem algebraically?” “What does each term in your equation represent?”
