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

In a Year 6 mathematics lesson on algebra, students are introduced to solving simple one-step equations using practical resources such as cubes, counters, and cups. The lesson aims to solidify their understanding of the four basic operations and how they apply to algebraic equations. The class begins with a starter activity where students review previous concepts, followed by a class teaching input that uses visual representations to help children grasp the concept of unknown values, represented by symbols such as 'x'. For example, they might explore how many counters are equivalent to a teddy bear, writing and solving an equation like 2x = 6 if each teddy is worth 3 counters. Further activities include solving equations represented by bread rolls and doughnuts, encouraging students to use substitution and formulae to find different values.

As the lesson progresses, students engage in partner discussions, group work, and independent learning through differentiated worksheets. They are challenged to match equations with their corresponding bar models and solve for the unknown variable 'm'. Key questions prompt students to think critically about the setup of an equation on a balance and how this visual helps in solving it. The lesson addresses common misconceptions, ensuring students understand the importance of maintaining balance by performing inverse operations on both sides of the equation. By the end of the lesson, students reflect on the skills they've used and the concepts they've learned, promising to remember the balancing method for solving one-step equations. Differentiated learning outcomes cater to varying levels of understanding, from writing simple equations to solving more complex algebraic problems.
