Factorising Expressions

PROCEDURAL
MathematicsAlgebra|Ages 12—13|ID: mt_uESbzWCZIq

Factorise algebraic expressions by taking out common factors — identify the highest common factor of all terms and write the expression as a product, e.g., 6x + 9 = 3(2x + 3)

Mastery Evidence

  • Identify the highest common factor of all terms in an expression
  • Write the factorised form as a product of the HCF and a bracket
  • Check factorisation by expanding the brackets back out

Assessment Prompt

“Can [child] look at an expression like "6x + 9" and rewrite it with the common factor taken out — as "3(2x + 3)"?”
