Tutero's expansion lesson introduces students to the process of expanding algebraic expressions using distributive properties. Students learn techniques for expanding single and multiple brackets, as well as simplifying the resulting expressions. By working through progressively challenging problems, students build their ability to manipulate algebraic expressions, which is essential for higher-level mathematics and problem-solving.
This lesson plan on expansion features enabling prompts to help students grasp the basics of expanding single binomials, complemented by extending prompts for those prepared to explore the expansion of more complex polynomials and their applications. The prompts are designed to foster a deeper understanding of algebraic processes, enhancing students' ability to manipulate and simplify expressions.

Introduction to Expansion
Students begin their journey into algebraic expansion by understanding the distributive property, which forms the basis for expanding expressions. They start with simple scenarios like expanding expressions a(b+c), using concrete examples to visualise the distribution of multiplication over addition. This concept is incrementally developed as they move through the grades, from using numerical examples to incorporating variables. By Year 5, students are familiar with the concept of expansion in various forms, including the ability to expand and simplify expressions involving multiple terms and variables.
Basic Expansion Techniques
Initially, students learn basic expansion techniques involving single-variable expressions and simple binomials, such as expanding (x+3)(x+4). They practice these skills using area models, algebra tiles, or simple multiplication, helping them visualise how each term interacts when multiplied. As they progress, they deal with more complex polynomials and learn to apply these techniques more broadly, including working with coefficients and combining like terms. By Year 5, students confidently use expansion techniques to tackle higher-degree polynomials and apply these skills in solving algebraic equations and simplifying expressions.
Expansion in Algebraic Terms
After mastering basic expansion techniques, students start to apply these skills to algebraic terms, learning to recognise and utilise opportunities for expansion in solving algebraic equations and simplifying expressions. They explore how expansion can be used to transform algebraic expressions into equivalent forms that are easier to manipulate or solve. This includes expanding products of binomials and trinomials, as well as applying expansion to solve word problems that involve algebraic reasoning. By Year 5, students can perform complex expansions and apply these skills in diverse algebraic contexts, preparing them for more advanced studies in algebra, including factoring and solving quadratic equations.
