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

In a structured lesson plan for Year 6 students, the focus is on enhancing their algebraic skills by teaching them how to solve two-step equations. The lesson utilises a variety of resources, including concrete objects like cubes and counters, worksheets, and a presentation. The key vocabulary introduced includes algebra, equations, and bar model, with resources available to support understanding. The session starts with a recap of one-step equations before moving on to more complex two-step problems. Through activities, students use concrete resources to visually represent and solve equations such as 5m + 3 = 23, documenting their algebraic workings alongside. This hands-on approach is designed to solidify their understanding of the algebraic process and the importance of maintaining balance on both sides of the equation.

The lesson progresses with the introduction of the bar model as a visual tool to represent the steps in solving an equation. Students engage in partner discussions to translate the visual representations into algebraic steps, exploring equations like 2x + 5 = 12 and adapting the bar model to find the value of x. Further practice is provided through group work and independent activities, which are differentiated to cater to varying levels of fluency and reasoning abilities. The lesson aims to address common misconceptions and reinforce the concept that actions performed on one side of the equation must be mirrored on the other to maintain balance. The plenary includes a reflective 'Give me five' session, where students evaluate what they have learned, the skills they have used and found challenging, and the strategies that aided their learning, ensuring they remember the key points from the lesson.
