Algebra - Solve Simple (Two-step Equations) - Starter

During a Year 6 maths lesson focusing on algebra, students are challenged with solving two-step equations. The lesson begins with a 'Fluent in Four' revision exercise to warm up their mathematical skills. For instance, they might calculate the product of 253 and 5, or find the result when doubling 139 and then multiplying by half of 6. Additionally, they are presented with a graph showing pulse rate changes during exercise, and they must determine the time it took for the pulse rate to reach its lowest point. In a practical context, students consider a scenario where Grace visits a sports shop and purchases two items, prompting them to calculate the maximum and minimum amounts she could spend.

The core activity of the lesson involves matching different algebraic equations to corresponding bar models, which visually represent the equations, and then solving for the variable 'x'. Equations such as 6x = 18, 4 + 2x = 18, and 3x + 6 = 18 are paired with their respective bar models, and students work out the value of 'x' for each one. This exercise not only reinforces their understanding of algebraic manipulation but also helps them to visualise the relationship between equations and models. The lesson concludes with a review of the solutions, where 'x' is found to be 3, 7, and 4 for the given equations, and an affirmation of the correct matches between the equations and the bar models, ensuring a comprehensive grasp of the concepts.
