Expressions and equations

In this unit, pupils learn about generalisation and formal algebraic manipulation techniques such as substitution, collecting like terms and factorising.

This is an attributed Oak National Academy lesson sequence, not a completed or academically approved DASKEREL course. Supporting transcripts may depend on video, images, practical equipment or teacher explanation. Follow each lesson’s supervision guidance. For religious education and RSHE, follow the school’s syllabus, policy and safeguarding procedures.

  • Use and interpret algebraic notation, including: ab in place of a × b 3y in place of y + y + y and 3 × y a² in place of a × a, a³ in place of a × a × a; a²b in place of a × a × b a/b in place of a ÷ b coefficients written as fractions rather than as decimals brackets
  • Substitute numerical values into formulae and expressions, including scientific formulae
  • Understand and use the concepts and vocabulary of expressions, equations, inequalities, terms and factors
  • Simplify and manipulate algebraic expressions to maintain equivalence by: collecting like terms multiplying a single term over a bracket taking out common factors expanding products of 2 or more binomials
  • Model situations or procedures by translating them into algebraic expressions or formulae and by using graphs
