Using Algebraic Formulae — Interactive Lesson (Ages 10–11)

Still explaining what to do with a letter in a maths question? This 19-slide interactive lesson gives Year 6 pupils focused, self-marking practice substituting values into algebraic formulae and working out the result.

Mastering Algebraic Formulae in Year 6 Maths

Pupils practise substituting numbers into simple algebraic formulae and calculating the outcome, building the early algebraic fluency within the Year 6 National Curriculum area of algebra. This substitution skill is the foundation nearly every later algebra topic builds on, so getting it genuinely secure in Year 6 pays off well beyond primary school.
